An advantage of the "wasted variable" (I prefer to think it is an "intelligently used variable") is that you can perform a little validation:

my $object = bless {hi => 'hello'}; for my $suffix ('x', 'y') { my $method = $object->can("prefix_$suffix"); $object->$method() if $method; } sub prefix_x { my ($self) = @_; print "$self->{hi} world\n"; }

Update: elaborate code to better show intent.

True laziness is hard work

[choroba]: act.yapc.eu
[robby_dobby]: Thanks, choroba
[LanX]: yes and Egypt (like Turkey and Russia) belongs to two continents
[choroba]: Also Europe and Asia are geographically one continent, the division is political
[robby_dobby]: I always thought everything on the other side of Suez to be Africa. That's an entire continent
[LanX]: Sinai_Peninsula
[robby_dobby]: choroba: If you're talking of Eurasia, it's only true of the erstwhile Constantinople/ Ottoman empire
[LanX]: yes correct, but Sinai is not on the other side
[LanX]: Organizing a YAPC in a tourist ressort is not a bad idea ...
[LanX]: ... and we could swap to our first YAPC Africa the following year when organizing in Hurghada
