The method invocation with the trailing parenthesis is
consistent with
the Perlish invocation of subroutines as "fun" or
"fun()". I think
this derives from the similarity with shell languages which
avoids
unnecessary characters, just as the syntax for list
functions:
         print "a ", "b ", "c
", "n"
rather than
         print("a ", "b ", "c
", "n")

Even C - although

As a matter of fact, you have the ugly

            $object->can('attribute')
and
            $object->can('method')

where there is no difference between attributes and methods
(because
you really didn't need to know it for sure -- it is a matter
of
implementation).

And that does not work all the time because the method can
be
implement by AUTOLOAD.

It is different in Javascript, Scheme and C because these
languages
avoid the kind of many ways to express a thing that Perl is
so fond
of.
