Hi monks,

My friend and colleague ChOas and I were having a little contest
here. We dared each other to write the shortest sub, returning the
index-number of the supplied element in an array
We came up with the following ... 
#!/usr/bin/perl -w

sub indexArray($@)
{
 my $s=shift;
 $_ eq $s && return @_ while $_=pop;
 -1;
}

my @array=('john','paul','ringo','george');

print indexArray('john',@array) ."\n";      # Returns 0
print indexArray('ringo',@array) ."\n";     # Returns 2
print indexArray('mick',@array) ."\n";      # Returns -1

Is anyone bored enough to participate in this silly contest?
Anything, shorter, funnier, more obfuscated ... will do and
is welcome ;-)

If you do not want to participate because you think this is too
silly and a waste of your time, then please don't, cause you're
right ! ;-)

Bye, Leon
