Alex Crichton 5e4bac31b8 rustc: Disallow modules and macros in expansions ... This commit feature gates generating modules and macro definitions in procedural macro expansions. Custom derive is exempt from this check as it would be a large retroactive breaking change (#50587). It's hoped that we can hopefully stem the bleeding to figure out a better solution here before opening up the floodgates. The restriction here is specifically targeted at surprising hygiene results [1] that result in non-"copy/paste" behavior. Hygiene and procedural macros is intended to be avoided as much as possible for Macros 1.2 by saying everything is "as if you copy/pasted the code", but modules and macros are sort of weird exceptions to this rule that aren't fully fleshed out.
