in thread Is it ok to mix functional and oo programming in one package?

Ah, but wait, you didn't write 
hello $a;

Why's that? It works ;-)

But when there's a hello sub in package main, then _that's_ the one that gets called, so it's not as if the advice is completely unjustified. 

#!/usr/bin/perl

use warnings;
use strict;

package Foo;

sub new {
    return bless {},shift;
}

sub hello {
    print "hello";
}

package main;

sub new {
    print "haha";
    return;
}

sub hello {
    print "Hi, $_[0]!";
}

my $a = new Foo;

hello $a;

__END__
Hi, Foo=HASH(0x814bd48)!

    True, but when I have an object instance, invoking instance methods using direct method invocation is, well, natural. I'd never think to do it any other way. But class methods on a bare-word...
