Summary: Misleading error message when using a member operator
with an incomplete type

Minimal example
Hello,
I found this (annoyingly) misleading error message.
When you use an operator of a type that is incomplete the error will not inform
you that the type is missing but that there is no such operator.
I would suggest that if an operator can not be found an additional check should
be made, that checks if all types that the operator is using are complete. If
one type is incomplete that should be the error message instead of the 'no
viable overloaded operator' one - or an additional note.
Attached you'll find a minimal example.
