in thread OO Perl: calling a constructor within a class

Were you thinking something like this?
Objects can always can, but a special can can can the usual can. But to see it's a special can you can:
$check_that_can_with = UNIVERSAL::can($obj,'can') ne \&UNIVERSAL::can;
But you can't catch the man who replaced the default can:
my $can = \&UNIVERSAL::can; local $^W = 0; *UNIVERSAL::can = sub { $_[1] eq 'can' ? \&UNIVERSAL::can : &$can; };
So can that man before he cans your can!

[marto]: the question is more, is Padre still the way new users should be directed?
[Discipulus]: ah ah I have all 5.26 atm but I play alone..
[Corion]: Except this RHEL box, which comes with Perl 5.10.1 , but there I installed my own 5.20.3 for the real Perl programs we run ;)
[Corion]: marto: I used Padre for some time but then switched to Notepad++, since all the funky features I wanted to put into Padre couldn't be made to work, and/or I lost interest :)
[Discipulus]: indeed marto I dunno. I tested once and many years ago. But I'm not the programmer yardstick. I try to install Padre via cpan now just to add a line about it in the issue. Strawberryperl all life long!
[marto]: yeah, when I worked on Windows I did use Np++ all the time

    Should cpanminus be part of the standard Perl release?
