Indeed, I used that workaround of manually nesting the functions in some code of 
mine:
https://github.com/WebDrake/Dgraph/blob/master/dgraph/graph.d#L492-L516

... but that's not a general solution, I was able to tolerate it because it's a 
limited and predictable set of instructions.

Jacob Carlborg suggested using opDispatch (cf. how it's done in Proxy), which 
should automate the "nesting" of template functions.  I avoided it simply 
because in my case I thought that doing it manually would be less hassle than 
getting opDispatch set up to cover every possible case, but depending on your 
use case it might be the better option.
