How about allowing it only inside parenthesis?
That works but breaks more valid code. -- Andrei
If the comma expression operator is outlawed on the global scope,
variadic template parameters could be used with commas outside the
parantheses which allows such syntax:
if(pMgr->ShouldRecordEvent(eSE_Weapon), pOwnerRaw) // ERROR
return pMgr->RecordEvent(eSE_Weapon), pOwnerRaw; // ERROR
if(e!pMgr->ShouldRecordEvent(eSE_Weapon), pOwnerRaw) // OK
return e!pMgr->RecordEvent(eSE_Weapon), pOwnerRaw; // OK
Would it make sense to reserve the global e identifier for expressions?
I'd be happy to see commas go and eventually wake up to this in a few
years, also enabling what would seem like a new kind of comma operator
overloading
