Details:

Suppose I have a classdef block which defines a "myclass", which defines a
"length" method.  If I call "print_usage" from within "length", it fails.  For
example:


length(L, 2)
error: 'fullname' undefined near line 55 column 33
error: called from
    print_usage at line 55 column 16
    length at line 168 column 5


On the other hand, methods of the class defined in external .m files (e.g., in
"@myclass/foo.m" rather than within the classdef block) can successfully call
print_usage.

I can cook up a minimal nonworking example if needed.
