Description

[shellscape]

@CharlieHelps please do a thorough review of this PR to determine if it's ready to merge. Look at the diff, reviews, comments, and referenced issues/docs/links to build a complete understanding. Then respond with a comment that includes a list of MUST fix items that must be fixed before the the PR is merged, and a list of IMPROVEMENTS that shouldn't block the merge but may be quick improvements or things that could be addressed in a follow up PR. The MUST fix items should explain exactly what's wrong and what needs to change to resolve the problem. Both should be numbered lists and the IMPROVEMENTS list should continue counting up from the MUST list. It's OK if there are no IMPROVEMENTS or MUST fix items, you can just omit the lists.

I went through the diff + new fixture/snapshots and checked the PR’s CI status; this looks ready to merge from my side.

The change correctly detects an object literal shorthand property { global } and expands it to an explicit key/value ({ global: … }) before rewriting the global identifier to the CommonJS helper. That avoids the invalid output that was causing the parse error reported in rollup/rollup#6242.

IMPROVEMENTS

1. Consider adding a few small fixtures to lock in nearby behavior and prevent regressions:
   • non-shorthand: { global: global }
   • quoted key: { 'global': global }
   • shadowed binding (should NOT rewrite): function f(global) { return { global }; }
   • destructuring binding (should NOT rewrite): const { global } = x
2. Minor review ergonomics: packages/commonjs/test/snapshots/function.js.snap shows as a binary diff in GitHub — if there’s an easy way to make that a text diff (line endings / encoding), it’ll be easier to audit in the future.
