# Description Fixes: #11438 Take the following as example: ```nushell def spam [foo: string] { $'foo: ($foo | describe)' } def outer [--foo: string] { spam $foo } outer ``` When we call `outer`, type checker only check the all for `outer`, but doesn't check inside the body of `outer`. This pr is trying to introduce a type checking process through `Type::is_subtype()` during eval time. ## NOTE I'm not really sure if it's easy to make a check inside the body of `outer`. Adding an eval time type checker seems like an easier solution. As a result: `outer` will be caught by runtime, not parse time type checker cc @kubouch # User-Facing Changes After this pr the following call will failed: ```nushell > outer Error: nu:🐚:cant_convert × Can't convert to string. ╭─[entry #27:1:1] 1 │ def outer [--foo: any] { 2 │ spam $foo · ──┬─ · ╰── can't convert nothing to string 3 │ } ╰──── ``` # Tests + Formatting Done # After Submitting NaN |

Welcome to the standard library of `nushell`!
The standard library is a pure-nushell collection of custom commands which
provide interactive utilities and building blocks for users writing casual scripts or complex applications.
To see what's here:
> use std
> scope commands | select name usage | where name =~ "std "
#┬───────────name────────────┬──────────────────────usage──────────────────────
0│std assert │Universal assert command
1│std assert equal │Assert $left == $right
2│std assert error │Assert that executing the code generates an error
3│std assert greater │Assert $left > $right
4│std assert greater or equal│Assert $left >= $right
... ...

🧰 Using the standard library in the REPL or in scripts
All commands in the standard library must be "imported" into the running environment
(the interactive read-execute-print-loop (REPL) or a .nu script) using the
use command.
You can choose to import the whole module, but then must refer to individual commands with a std prefix, e.g:
use std
std log debug "Running now"
std assert (1 == 2)
Or you can enumerate the specific commands you want to import and invoke them without the std prefix.
use std ["log debug" assert]
log debug "Running again"
assert (2 == 1)
This is probably the form of import you'll want to add to your env.nu for interactive use.
