That's a weird use of a query method. In fact, that sounds like a
normal method call. Applied to some other situations:
# "What would @list look like if it were sorted"
@sorted_list = @list.sort?
# "What would this filehandle look like if it were open"
$open_fh = $fh.open?
I expect query methods to be simple yes/no questions that return
true/false. @list.sort? should return whether or not the @list were
sorted (not that this is particularly useful) and $fh.open? to tell me
if the filehandle is open or not.
I think the function/method distinction is a better seperation between
"what would this thing look like if it were acted on" and "act on this
thing".
# What would this look like if it were sorted?
@sorted_list = sort @list;
# Sort this list
@list.sort

Me? A robot? That's rediculous! For one thing, that doesn't compute at all!
