Real world example: [*]
[EMAIL PROTECTED]:~> perl -MTest::More -MMath::String -wle 'plan tests => 1; $a =
Math::String->new("abc"); $b = $a->copy()->bneg(); ok $a,$b; print "$a != $b
(", $a->as_number(), " != ", $b->as_number(),")";'
1..1
ok 1 - abc
abc != abc (731 != -731)
ok() considers them equal, since it uses "eq" internally. Should is_deeply()
also consider them equal? Good question, I have no idea, never having uses
is_deeply().
Best wishes,

*: Math::String objects are dualities, they have a string and a number
representation. Now, there is a 1:1 mapping, except all negative numbers give
the same string as positive ones. In praxis, this is usally ignored when
talking about the 1:1 mapping, though.
