I was working on creating a crate and encountered some unexpectedly long compile times.
I don't have a minimal reproduction, but I have expanded my macros, and copied the code into a playground.
It occurs on all channels. It is still pretty bad even with the parallel front-end enabled. According to time-passes, the biggest culprits were coherence checking and type checking.
time: 6.038; rss: 80MB -> 272MB ( +192MB) coherence_checking
time: 6.084; rss: 80MB -> 274MB ( +195MB) type_check_crate
My use case is clearly atypical, so I will understand if you consider this frivolous and close it. (Although, when I searched to see if my issue had already been reported, I did notice submitted situations that were arguably even less likely to be encountered by anyone.)
