Recommend holding until after #13125 is fully digested and *possibly* until 0.96. # Description Fixes one of the issues described in #13125 The `do` signature included a `SyntaxShape:Any` as one of the possible first-positional types. This is incorrect. `do` only takes a closure as a positional. This had the result of: 1. Moving what should have been a parser error to evaluation-time ## Before ```nu > do 1 Error: nu:🐚:cant_convert × Can't convert to Closure. ╭─[entry #26:1:4] 1 │ do 1 · ┬ · ╰── can't convert int to Closure ╰──── ``` ## After ```nu > do 1 Error: nu::parser::parse_mismatch × Parse mismatch during operation. ╭─[entry #5:1:4] 1 │ do 1 · ┬ · ╰── expected block, closure or record ╰──── ``` 2. Masking a bad test in `std assert` This is a bit convoluted, but `std assert` tests included testing `assert error` to make sure it: * Asserts on bad code * Doesn't assert on good code The good-code test was broken, and was essentially bad-code (really bad-code) that wasn't getting caught due to the bad signature. Fixing this resulted in *parse time* failures on every call to `test_asserts` (not something that particular test was designed to handle. This PR also fixes the test case to properly evaluate `std assert error` against a good code path. # User-Facing Changes * Error-type returned (possible breaking change?) # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting N/A |

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.
