[Octave-bug-tracker] [bug #57255] "+=" not parsed correctly in anonymous function within cell array context

[John W. Eaton]

Follow-up Comment #3, bug #57255 (project octave):

In Matlab, assignment is a statemnet, not an expression, and only expressions
are allowed in anonymous functions.

Although the error message is not as informative as it could be, we already
disallow assignment expressions in anonymous functions.  It seems more of an
oversight that the parser accepts expressions that use compound assignment and
increment/decremnent operators.

Sorry, but I don't think we should attempt to do anything more here except
also generate errors for increment/decrement and compound assignment operators
and improve the error message.
