The D programs that compile after the fix that wouldn't have compiled before.

Indeed, but in order to fix this issue, we need a computationally decidable
notion of dependence of function return types.

Currently, this is quite conservative. Analysis of any function is suspended if
a function call with unresolved return type is encountered, until this return
type has been resolved.
