WebThat's correct. I think the lexical decl context is correct here (it really is lexically in the TU) and the issue is that we need to fallback to some other string for contexts other than a CXXRecordDecl.I think the TU might be the only case we have to worry about here -- I don't think there's a way to shove that defaulted definition into a namespace or some other … WebApr 7, 2024 · The false operator returns the bool value true to indicate that its operand is definitely false. The true and false operators aren't guaranteed to complement each other. That is, both the true and false operator might return the bool value false for the same operand. If a type defines one of the two operators, it must also define another operator. leeds and wetherby cricket league
