No. D doesn't have something like C++'s ADL where the template 
arguments lead to additional names being introduced into the 
scope of the template body. This is by design.

Sorry, I don't quite get what you mean here. The error is just a 
follow-up to the previous one, as the inability to look up Foo 
caused an error while instantiating that template.

Maybe you can elaborate a bit on how the problem occurs in that 
context? As I said, I've found that usually it is possible to 
come up with a design at least as pretty (or even prettier) but 
doesn't rely on stringof trickery if one just stares at the 
problem long enough. ;)
