Trying to understand semantic-analyze-scoped-types, which never returned 
anything different than nil for me, I came across 
semantic-ctxt-scoped-types, which is only non-nil in c++-mode. I was 
unaware that namespaces are an c++-only feature. So the above example 
was in a c-file, in c mode... In c++ mode everything works fine as 
expected.

Understanding this also helps to fit Fortran into C structure: For a 
function, subroutine or program, which has a contains part, create a 
"contains" tag of class type and :type "contains" and return those tags 
by overloadable semantic-ctxt-scoped-types. At the moment, functions and 
subroutines residing in a contains sections of an encompassing function, 
subroutine or program are tags in the members list of this encompassing 
tag, and hence the encompassing function, subroutine or program would 
act like a hybrid of class 'function and 'type at the same time, which 
does not fit well into the current framework.
