An very similar problem exists for int and char overloads:

Wait a minute! This doesn't appear to be a casting or
overload problem. Can you really overload aliases in D?
In fact, I'm surprised you can alias to an expression like
that. Usually you need a symbol. It's probably due to how this
is lowered.
Boy did I "step in it" with my original post: Started out with
one issue and ended up with 3.
I looked at what the compiler is doing, and it is generated a new
symbol (e.g. `__lambda4`). I suspect this is not intended.
My question now is, should the compiler actually be treating the
lambda as an expression instead of a new symbol, thus disallowing
it altogether? (sigh! more breakage)?
