I think there was some misunderstanding on my side as I was interpreting
c-end-of-defun as c-end-of-*named*-defun.  This means I was not
considering lambda as an unnamed function but just as a default
argument.

Yes, C++ can get really ugly sometimes.

The main moto behind my "feature request" was not solving the problem
logically but to be so called "contributor" of GNU Emacs.  Apology for
that.
