What would be the form of "is" expression to match with a Variadic
Template
Class?
I am pasting a simple example below to clarify my need. I need an is
expression to match with the Bar(T...) type in the code below.
Regards
- Puneet
class Foo(int N=0) {}
class Bar(T...) {}
void foobar(L) (ref L l)
if(is(L f : Foo!N, int N))
{
import std.stdio;
writeln("Matched a Foo(int N)");
}
void foobar(L) (ref L l)
if // WHAT IS EXPRESSION SHOULD COME HERE
is(L unused : Bar!T, T...)
{
import std.stdio;
writeln("Matched a Bar(T...)");
}
void main() {
Foo!0 foo = new Foo!0();
Bar!() bar = new Bar!();
foobar(foo);
foobar(bar);
}
