The compiler segfaults for any single mistake inside certain template code.
import std.typecons;
Tuple!(Types) foo(Types...)(string a)
{
typeof(return) result;
mistake;
return result;
}
void main()
{
auto a = foo!(int, double)("a");
}
The compiler's answer is:
Segmentation fault
The 2.x compiler is next to unusable for writing template code at this time. Please go back in time last week and fix this bug.
