[Octave-bug-tracker] [bug #43925] isscalar behaves incorrectly for some user-defined classes

[Lachlan Andrew]

Follow-up Comment #14, bug #43925 (project octave):

I also found it odd that  size()  isn't const.

I didn't raise it because it is difficult to change.  There is probably code
out there that overloads the non-const size().  If we make size() const, that
code will fail in complicated ways.  That is even true if we have both a const
and non-const size(), and we use the const one.

However, that is just my opinion.  I haven't seen it discussed on the mailing
list, but it would be great to hear what others think.
