I'm of two minds.. in some ways perls contextual returns are lovely and DWIM..
but in other cases I'd really rather it required me to be specific.

DBIC actually gets around this by having a context ignorant accessor.. adding
_rs to accessor methods (search, relationships) will force list context and
give you back an iterator rather than getting clever with wantarray.
