The following code doesn't compile because the generated type

Fowarded to implementation of makeWith below
}
auto makeWith(T, Args…)(auto ref Args args) … // This is the

The idea is that users could type (for example)
makeWith!`Calendar`(…) instead of the longer
makeWith!ICalendarFactory(…).
I tried mixing in an import statement with the help of
std.traits.moduleName so that the I...Factory type would be
available but again the compiler complains that it's undefined.
Has anyone had a similar need and come up with a solution?
you need to qualify the names: I use
https://github.com/libmir/dcompute/blob/master/source/dcompute/driver/ocl/util.d#L77-L97
for this in dcompute (needs to be updated for the new style of
mixin but you get the idea).
