Rust Bikeshed tailcall
View Bikeshed-tailcall.md

This page is for collecting ideas around axing or implementing tail calls in rust. The current status of this issue is undecided after a longer discussion on the list in jul/aug 2001. (There currently is no consensus on the matter nor is this page a complete summary of that thread, I am just writing down a few own thoughts right now but the page may very well become that -- boggle)

Pro/Con

  • Pro: Obvious uses in functional programming (But: Replacable with iterators/blocks in many cases)
  • Pro: People expect that in a language that says to support functional programming with immutability as a default (But: Well
    that really just is a sales argument and should not steer design)
  • Pro: Simple, forwarding functions don't pay the cost of an extra stack frame
    • this is currently used in core::float to pass calls on to core::f32 and core::f64 depending on the target
      architecture (even though "be" is not really implemented)
