--- Comment #3 from Walter Bright <bugzi...@digitalmars.com> --- (In reply to Sobirari Muhomori from comment #1) > Shouldn't the argument be destructed by the caller when the callee returns? Yes. Once the function gets called, it gets marked by the compiler as "don't destroy this". > So it couldn't be constructed in place anyway. --
