• Martin Cejp (10/10) Jan 25 2014 I'm trying to do something to this effect:
• Rikki Cattermole (2/12) Jan 25 2014 Class.stringof perhaps?
• Jason White (3/4) Jan 25 2014 Damn, beaten by 1 second!
• Jason White (9/9) Jan 25 2014 I think what you are looking for is Class.stringof:
• Dicebot (5/15) Jan 25 2014 for just printing `Class.stringof` is most simple thing to do.
• Martin Cejp (4/21) Jan 25 2014 Thanks, that will do.

template XYZ(Class) {

However, typeid is not a string and I can't do to!string. Nor is 
typeid().name implemented at compile time.
What would be the correct way to do this?

for just printing `Class.stringof` is most simple thing to do. 
There are also `__traits(identifier, Class)` and 
`std.traits.fullyQualifiedName!Class` that are more specialized 
and usually used in code generation.

Thanks, that will do.
fullyQualifiedName was the first that came to mind, but it's 
broken.

I'm starting to like this language :-)
