Follow-up Comment #15, bug #32533 (project octave):

I started trying to write new parser tests against the new documented behavior
and came across this:


a = 1;
b = 2.^a++

Under 3.4
b = 2, a = 2

On stable branch w/latest precedence patch
error: invalid lvalue function called in expression


I think the 3.4 behavior is correct since a++ should return 1 to the current
expression being evaluated while incrementing the variable a only after the
entire expression has been evaluated.
