While I agree with Simon that this patch is fine, I think the intended
design of eval.c is that skipped expressions should still try to return
a value of the correct type when possible.  The reason for this is that
the type is still sometimes needed, for example to compute the correct
type of a ?: ternary operator, which in turn could be used for overload
resolution.

This sounds like a bug to me.
