Hi,
I try to make a class template with single template argument
defaulted to some type.
Is it possible to use the name of class without specification
of template argumet (no '!' operator)?
Example:
class ClassName(T=double) {
this(T value) { /// do some stuff here
}
/// some other stuff..
}
void main() {
a = ClassName(1.2); /// error: cannot deduce function from
argument types !()(int)
a = ClassName!double(1.2); /// OK
}
It seems the compiler treats 'ClassName' as function, but it is
obvious that it should treat it as 'ClassName!double'.
No, you'd have to at least write
auto a = new ClassName!()(1.2);
Or you could define a make function:
auto makeClassName(T = double)(T value) {
return new ClassName!T(value);
}
auto a = makeClassName(1.2);
