I personally do not see the connection, but even if I did I would
still respectfully disagree. This "wrong signal" would only be sent in
the case that someone (a) has some knowledge of C so that they know what a
string is "under the hood" and (b) is enough of a Perl newbie to not
understand that length is not used to get the number of elements in an
array. That means that (1) anyone who does _not_ have C experience will
not have this problem, (2) anyone who is moderately experienced at Perl
will not have this problem. As soon as someone discovers that
print("100"+2) is valid in Perl and prints 102, they should realize that
Perl is different from C.
