in == scope const not sure what scope buys here but couldn't hurt.
If it can avoid making a new copy, then it likely would help. I'll
need to test it. I actually am not quite sure how scope works as an
argument; it isn't really covered in TDPL from what I recall.
Tests with 'in' doesn't help, only ref and catching a temporary seem
to prevent postblits.
Also the empty template doesn't work, somehow I'm not surprised...
template X(bool something) {
struct XT {
Fixed :
void func(bool smth)(X!(smth).XT x){
By default XT is deduced as X!(current value of smth).XT
writeln("XT template called: typeID:", typeid(x));
}
}
}
alias X!true.XT A;
alias X!false.XT B;
A a, b;
B ba;
a.func(b); //passes
a.func(ba);
Error: template test.X!(true).XT.func does not match any function
template declaration
Error: template test.X!(true).XT.func() cannot deduce template function
from argument types !()(XT)
