When you need to get the name of the enumerated value, you have to use the 'to'
template function from std.conv, as described in TDPL. Your example then
becomes:

import std.conv : to;
import std.stdio: writeln;
void main() 
{
    enum Foo { Zero, One }
    Foo f = Foo.One;
    writeln(to!string(f));
}

Prints: One

It wouldn't make much sense for an enum to behave differently in different
contexts (e.g. comparing it in an if statement vs. using it with a writeln).
