    file.d(1): Error: variable file.lam3 type void is inferred from initializer
(x, y) => x + y, and variables cannot be of type void

The error is confusing because templates internally have the type void.

We don't plan to support auto variables with polymorphic lambdas, because just
as you said, there is no actual variable/data involved.

There is a pull request to enable the alias syntax.

That I don't understand.
