``set`` requires all options to come before any other arguments. For example, ``set flags -l`` will have the effect of setting the value of the variable ``flags`` to '-l', not making the variable local.
In assignment mode, ``set`` does not modify the exit status. This allows simultaneous capture of the output and exit status of a subcommand, e.g. ``if set output (command)``.
