Hi,

Is this a bug?

import std;

template test(alias f) {

    auto test(I)(I i) { return f(i); }
}

void main()
{
    alias t = test!(x=>x+1);
    1.t.writeln; //<--Doesn't compile
    1.test!(x=>x+1).writeln;
    t(1).writeln;
}

}

Not a bug. Local symbols can't be used as UFCS functions.

Thanks very much. I left wondering why that design decision was made.
