 Examples:
 
 - Here documents are too similar to using echo inside of a pipeline.
+
 - Subshells, command substitution and process substitution are strongly related. `fish` only supports command substitution, the others can be achieved either using a block or the psub shellscript function.
+
 - Having both aliases and functions is confusing, especially since both of them have limitations and problems. `fish` functions have none of the drawbacks of either syntax.
+
 - The many Posix quoting styles are silly, especially $''.

+
+\section design-response The law of responsiveness
 
 The shell should attempt to remain responsive to the user at all times, even in the face of contended or unresponsive filesystems. It is only acceptable to block in response to a user initiated action, such as running a command.
 
 Rationale:
-
 Bad performance increases user-facing complexity, because it trains users to recognize and route around slow use cases. It is also incredibly frustrating.
 
 Examples:
 
 - Features like syntax highlighting and autosuggestions must perform all of their disk I/O asynchronously.
+
 - Startup should minimize forks and disk I/O, so that fish can be started even if the system is under load.

 Rationale:
-
+Different configuration options are a nightmare to maintain, since the number of potential bugs caused by specific configuration combinations quickly becomes an issue. Configuration options often imply assumptions about the code which change when reimplementing the code, causing issues with backwards compatibility. But mostly, configuration options should be avoided since they simply should not exist, as the program should be smart enough to do what is best, or at least a good enough approximation of it.

 Examples:
 
 - Fish allows the user to set various syntax highlighting colors. This is needed because fish does not know what colors the terminal uses by default, which might make some things unreadable. The proper solution would be for text color preferences to be defined centrally by the user for all programs, and for the terminal emulator to send these color properties to fish.
+
 - Fish does not allow you to set the history filename, the number of history entries, different language substyles or any number of other common shell configuration options.

Both zsh and bash support command specific completions, but no such completions are shipped with bash by default, and they are turned off by default in zsh.

-intuitive and powerful program. Implementation issues should only be
-considered once a user interface has been designed.
 
 Rationale:
-
+This design rule is different than the others, since it describes how one should go about designing new features, not what the features should be. The problem with focusing on what can be done, and what is easy to do, is that to much of the implementation is exposed. This means that the user must know a great deal about the underlying system to be able to guess how the shell works, it also means that the language will often be rather low-level.

 Examples:
-
 - There should only be one type of input to the shell, lists of commands. Loops, conditionals and variable assignments are all performed through regular commands.
+
 - The differences between builtin commands and shellscript functions should be made as small as possible. Builtins and shellscript functions should have exactly the same types of argument expansion as other commands, should be possible to use in any position in a pipeline, and should support any io redirection.
+
 - Instead of forking when performing command substitution to provide a fake variable scope, all fish commands are performed from the same process, and fish instead supports true scoping.
+
 - All blocks end with the `end` builtin.

 - Fish `ulimit` does not support the `-p` option for getting the pipe size. The bash implementation consists of a compile-time check that empirically guesses this number by writing to a pipe and waiting for SIGPIPE.
