The name is misleading because you want types other than string as well.

That should have been a compilation error because 'toString' does not
have a known type (because it depends on a template parameter). How can
the compiler accept that 'alias this'?

Since you need to spell out 'int' and 'float' in some form anyway, the
following would be my choice, which I did use in my code before:
struct MyVal
{
private string value;
auto to(T)()
{
import std.conv : to;
return value.to!T;
}
}
void main() {
auto a = MyVal("100");
auto b = MyVal("11.2");
auto myInt = a.to!int;
auto myFloat = b.to!float;
}
Should it be an error to convert 'a' to float? If so, the following
modules may be helpful:
