There was a problem hiding this comment.
this sort of code duplication is very unfortunate, could we encapsulate that into a macro? (just the cfg + const switch)

(Feel free to copy a helper macro used in my crates if needed)

This PR makes
ConcurrentQueue::unboundeda const function. It'd be great ifboundedcould beconstas well, but this would likely require static memory allocation support in const functions, which is currently not allowed by the compiler. This would enable smol-rs/async-executor#112 to be directly constructable in a const context (i.e. static/thread_local variable initialization without OnceLock). It might also allow unboundedasync_channels to be constructed in a similar context.
