Actually I think it's not zero-arg functions.
The problem is that one of my arguments is a templated type.
The .stringof says the parameter type is TheTemplate, when the
argument type is really TheTemplate!(T).   So when your code tries to
generate the function it tries to make it    void
aFunction(TheTemplate x) { ... }, which obviously ain't gonna fly.

So looks like bad stringof is the culprit, once again.
