OK, of course it can't work. toObjFile has to be called on the
TemplateInstance, not on the declaration...

All TemplateInstances are currently emitted by Module::genobjfile which
loops through all Dsymbols in the module. Therefore the scope for
functions in template instances is always the module scope which is
incorrect.

A simple approach to fix this is delaying emitting those templates and
emitting functions first, then change function output to emit template
instances.
Here's this simple approach: https://gist.github.com/4524721

 //What should multiobj be?

multiobj is ignored by gdc, but just for consistency reasons, just go with false.

Also, do you find that templates must go after *all* functions have been processed, or is it fine if you just add them to toSymbol()->deferredNestedFuncs for the function they are associated with to be processed immediately afterwards.
