Description FeepingCreature 2020-04-21 11:15:44 UTC 
Repro:

static assert(is(ImplicitConversionTargets!(const A) == const Object));

Fails because ImplicitConversionTargets!(const A) is nonconst Object.

"Caused" by the PR https://github.com/dlang/phobos/pull/7313 for 15940 - previously, ImplicitConversionTargets for const classes would not give any result.
