Compile-Time Performance Issues & Suggestions

[geoffreygarrett]

Following the discussion in #3476—especially this comment by @94bryanr—we’re collecting compile-time performance concerns and workarounds here. If you’ve run into long build times, linker errors, or recursion limits, please share:

1. Reproducible Cases: Steps or minimal examples.
2. Workarounds: Crate splitting, using into_any(), alternative linkers, etc.
3. Suggestions: Ideas for framework or compiler changes that could help.

This thread aims to consolidate solutions and guide further improvements. Thank you for contributing!
