Hi all,
I'm hitting a problem that it's making crazy... is there any way to find
out if the return of an `auto ref` function is actually ref or not?
So, according to the documentation [1] it depends on the return
expressions... however in my case I'm implementing `opDispatch` in a
wrapper type (and trying to carry over the ref-ness), so I don't know
how can I check it.
Now, the whole point of this wrapper is to act differently based on
whether the return is a reference or not (it already checks for
`hasIndirections`, which btw doesn't help here either).
I've tried to use `__traits(isRef, ??? ) but I haven't been able to find
out how to use it, it seems to be meant for parameters. Perhaps it would
make sense to have something like `traits(isRef, return)`?
Also I have tried making two different overloads, with and without ref,
but it didn't work either...
