watch doesn't work as described

[solodov]

Describe the bug

Split of closures and blocks in 0.72 might have broken some built-in commands, watch in particular. Either that, or the documentation is out of date.

How to reproduce

1. run watch . { |op, path, new_path| $"($op) ($path) ($new_path)"}

Expected behavior

Should watch for file changes and log

Screenshots

〉watch . { |op, path, new_path| $"($op) ($path) ($new_path)"} 
Error: nu::parser::parse_mismatch (link)

  × Parse mismatch during operation.

Thanks for the bug report. I’ll take a look, should be an easy fix.

This is fixed in main now if you can build Nu from source. Otherwise the fix will come out in the v0.73 release on Dec 20. Sorry for the inconvenience!
