Summary

Follow-up to #147. Replace the generated wrapper's ASCII __args binding with the deterministic package-specific identifier ˍ₋rgf₋args.

This preserves deterministic generated source without a per-module gensym while making accidental capture of a user-defined __args function negligible.

Regression

Restore the __args MRE documented in #146. It fails on the merged master by attempting to call the argument tuple and passes with this change.

The fixed identifier is collision avoidance rather than complete hygiene: code that deliberately uses the exact name ˍ₋rgf₋args can still collide.

Verification

• Focused f and __args collision regressions
• julia --startup-file=no --project=. -e 'using Pkg; Pkg.activate("."); Pkg.test()'
• Runic v1.9.0 --check --diff --verbose over all 10 tracked Julia files

Checklist

• Tests added for the remaining collision
• Full local test suite passes
• Runic passes
• Public API is unchanged
• Documentation and version changes are not needed

Implementation log for commit d453982:

1. Fetched the merged master at 28fa8b0 and confirmed Gensym / remove the RGF name instead of using f and __args #147 removed the f wrapper binding but retained ASCII __args.
2. Replaced the helper formal, quoted tuple reference, generated vararg binder, and helper-call argument with the same deterministic ˍ₋rgf₋args identifier.
3. Restored the __args regression from Stack overflow when calling a function named f outside the RGF #146 beside the merged f regression.
4. Verified the identifier code points are U+02CD, U+208B, rgf, U+208B, args.
5. Ran focused collision checks, the full package test suite, and the repository's CI-matching Runic check.

Local results:

• Focused f and __args regressions: passed
• Pkg.test(): RuntimeGeneratedFunctions tests passed
• Runic v1.9.0 over all 10 tracked Julia files: passed

Next step: monitor the full GitHub Actions matrix and address any failures.
