Traits problem

[Daniel Ribeiro Maciel]

The strange part is that, for some reason, this works:


import std.stdio: writeln;

class Foo {
    float bla() { return 0.0; }
    void foo() {}
}

void exportObject( TClass, members... )()
{
    foreach( uint i, member; members )
        writeln( typeid(typeof(__traits(getVirtualFunctions, Foo, members[i]) )) ); 
}

void main() {
    exportObject!( Foo, "bla", "foo" )();
}
