------------------------------- ref int boo(); void main() { assert(( boo() = 2) == 2); } ------------------------------- Only with -checkaction=context: checkaction.d(5): Error: assignment cannot be used as a condition, perhaps `==` was meant?
@MoonlightSentinel created dlang/dmd pull request #12307 "Fix 21765 - Assignment-as-condition error with checkaction=context" fixing this issue: - Fix 21765 - Assignment-as-condition error with checkaction=context Don't eagerly check `toBoolean` if `op` is nested in another expression. This still catches `assert((a = 1))` but prevents invalid errors for assignments in `assert((a = 1) == 1)`. https://github.com/dlang/dmd/pull/12307
