It's not working for my case, while I see no special reason why
it couldn't. Also I can't find specific inference rules at
http://dlang.org/spec/function.html#function-templates
Is it a problem that the types to be inferred are in turn also
templated? Any workaround that can make inference wor

Interesting, thanks a lot. I'll test and narrow down what's in my
code preventing this from working (I can't really think of
anything) and I'll report b

Found it! It stops working (DMD v2.073.0 for Windows) if it has
to infer the type of a temporary local variable -- constructed in
place of the argument:

That's a common request but the solution is not implemented yet because
it's not trivial if you
