Re: Re: How called was &I?

method $obj $arg; is not an error.

"Classname"->method( $arg); 
method "Classname" $arg; 
method( "Classname", $arg);

The first two act just like the last one.

Not so. Consider:

#!/usr/bin/perl -w
use strict;

package Base;
sub base {
    print "Base::base called\n";
}


package Derived;
use vars qw( @ISA);
@ISA = ( "Base");


package main;

Derived::base Derived "hello";
Derived::base( Derived,"hello");   #  undefined
Derived::base "Derived" "hello";   # syntax error

`method $obj $arg;`is not an error. You are right. It isn't. I don't know what I was thinking. Before going on, I should clarify my point. Once a method is called, there is no way to determine the syntax used to invoke it. Your addition of a Derived class does nothing to show otherwise. That said, I made a couple of poor assumptions. One was that `"Classname"` in the original wasn't really meant to be a quoted string but a bareword. I also assumed that `method` would be the appropriate name for the method regardless of context. There really was no good reason to assume either and I should have requested clarification. `# Actual original post # What I assumed the OP meant "Classname"->method( $arg); # Class->method($arg); method "Classname" $arg; # method Class $arg; method( "Classname", $arg); # Class::method(Class, $arg);` [download] Mistakes, assumptions, and mistaken assumptions aside, if I understand the original post, the answer is still "No." -sauoq "My two cents aren't worth a dime.";	[reply] [d/l] [select]
