Question 2: Is there a "correct" way to do this? I possible,
I'd want to avoid
"nesting" the template, eg:
auto fun(){return Impl!int();}
As that would:
a) require more typing ^^
b) incur an extra function call in non-inline
c) if at all possible, I actually need "fun" to be a template,
so that it can be
inlined.
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.
Thanks. I'm not very fluent with opDispatch though. Doesn't that
only work if you have an struct/class instance though? My "fun"
is a free frunction.
I you are able to adapt it to my trivial usecase, it might be
clearer to me what you have in mind.
