Indeed. What about lists?
print length(qw(a b c));
Should this return 3?
If so, what will this return?
print length('abc');
Is the argument not a list of one item? So, should this print 1, or 3?
Note that similar functions that work on both scalars and lists, such as
reverse(), use the context in which it is called. so,
print reverse 'qwerty';
will still print 'qwerty', while
print scalar reverse 'qwerty';
prints 'ytrewq'.
Note that this trick can't be used here, because length() only returns a
scalar.
