alias PSC = ParameterStorageClass; alias PSCT = ParameterStorageClassTuple;
void fun1(return ref int){}
void fun2(return out int){}
PSCT!fun1 == (PSC.return_ | PSC.ref_) // false
PSCT!fun2 == (PSC.return_ | PSC.out_) // false
PSCT!fun1 == PSC.return_ // true
PSCT!fun2 == PSC.return_ // true
how to differentiate them?
