Module erase 

To improve compile times and code size for the compiler itself, query values are “erased” in some contexts (e.g. inside in-memory cache types), to reduce the number of generic instantiations created during codegen.

See https://github.com/rust-lang/rust/pull/151715 for some bootstrap-time and performance benchmarks.
