Declarative macro repetition counts about lang-team

[pnkfelix]

Just as a heads up: The essential idea proposed here was previously proposed (ages ago, prior to Rust 1.0) in rust-lang/rfcs#88. There may be value in double-checking the contents of that RFC PR and/or its associated comment thread.

(Update: I will put more specific feedback on this proposal, as informed by rust-lang/rfcs#88, directly on the zulip stream itself.)

This issue is not meant to be used for technical discussion. There is a Zulip stream for that. Use this issue to leave procedural comments, such as volunteering to review, indicating that you second the proposal (or third, etc), or raising a concern that you would like to be addressed.

One concern is that the $#var syntax conflicts with the quote! macro's syntax for substituting a variable, which is #var.

Can you do ## or something to get an "escaped" hash into the output?

Can you do ## or something to get an "escaped" hash into the output?

not according to the docs for quote!

Hey @rust-lang/lang -- we haven't seen anyone volunteering to serve as liaison for this project. If we're not able to find a liaison in the next week or so, I'm going to close the issue. If you think you might like to serve as a liaison, even if you don't have bandwidth right now, please do speak up -- we can always put the proposal on the "deferred list" to pick up when we have time.
