Thanks to input from the D community, I've managed to implement a
reasonable way to log the name of a calling function. This is used for
basic execution monitoring and for automated logging of exception errors.

Here's what I did.

template __FUNCTION()
{
    const char[] __FUNCTION = "__traits(identifier, __traits(parent, {}))";
}

Example use in code:

throw new Exception( "Error: Function ", mixin(__FUNCTION!()) );

writefln( "File: %s, Func: %s, Line: %d", __FILE__,
mixin(__FUNCTION!()), __LINE__ );

That's pretty darn cool, well done :D .
