Follow-up Comment #20, bug #54698 (project octave):

With your proposed change the transpose operator and the power operator have
different precedence. Considering the following expression:


a^b'


currently it is evaluated as (a^b)' but with your proposed change it should be
evaluated as a^(b') . Comment 11 has noted the related problem. 

Also I think that postfix ++/-- should have the same precedence as call
operator because in the expression a++(x) a postfix operator "++" is followed
by another postfix operator "()" that has lower precedence and it is syntax
error. Is it needed to be discussed in a separate bug ?
