# Description Fixes #14401 where expressions passed to `timeit` will execute twice. This PR removes the expression support for `timeit`, as this behavior is almost exclusive to `timeit` and can hinder migration to the IR evaluator in the future. Additionally, `timeit` used to be able to take a `block` as an argument. Blocks should probably only be allowed for parser keywords, so this PR changes `timeit` to instead only take closures as an argument. This also fixes an issue where environment updates inside the `timeit` block would affect the parent scope and all commands later in the pipeline. ```nu > timeit { $env.FOO = 'bar' }; print $env.FOO bar ``` # User-Facing Changes `timeit` now only takes a closure as the first argument. # After Submitting Update examples in the book/docs if necessary. |
