Not quite, "Foo" would be a template parameter, so something like 
this (which does not work, but maybe there is some other way to 
express it?):


struct Foo(T)
{
     T x;
}


void foo(T)(T!int x) {
     import std.stdio: writeln;
     writeln("here");
}

void main() {
     Foo!int x;
     foo(x);
}
