Did you perhaps mean `A` instead of `T` here? cuz in your code
T is int, not the struct.
I don't think I did :p
T is the wrapped type. So if T has a member (in the example
it's the built in field "max") then forward that. If member not
there then I figured the alias this would be used. I.e. in the
example b.p should call A.p.
I assume this should work because rules for alias this (as I
understand) are to basically try if there's a member name that
resolves the call, else forward to alias this.
There is a related ticket,
https://issues.dlang.org/show_bug.cgi?id=6434
However, not exactly facing this question.
It seems, that currently opDispatch replaces alias this... (?)
Nevertheless, not only T is the wrapped type, but also A with the
alias.
What to do, if both members have a property with the same name?
And why?
