Thanks!  I still want to look into why the simple version* doesn't work, but that at least solves my immediate problem.

* template isTuple(T : Tuple!(U), U...) { enum isTuple = true; }

This approach even gives an invalid line number for where the problem lies.  I'll also have to submit a bug report for the compiler.
