Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.

    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!
    (Sorry)

[stevieb]: shmem It's something I desired to have years ago, which is why I took over berrybrew. Cross-platform build/test automation locally, or over the network Test::BrewBuild
[shmem]: sounds good.

[stevieb]: I'm working on it to fatten it up and make it more reliant so I can finalize my Raspberry Pi automated build system for that software :) It's all well and fun, until I try to make it work with Windows lol
