Re: Default template arguments

Joseph Rushton Wakeling:

... or have I missed something?

Second try:

import std.stdio;

void printSize2(T)(T x) {
    writeln(T.stringof);
}

void printSize(T1 = void, T2 = real)(T2 x) {
    static if (is(T1 == void))
        printSize2!real(x);
    else
        printSize2!T1(x);
}

void main() {
    float x;
    x.printSize();       // shoud be real
    x.printSize!float(); // shoud be float
    x.printSize!real();  // shoud be real
}

Bye,
