Unfortunately, the following fails with this code:
zip( 'abcde', 'ABCDEFGHIJ' );
This is a good example of why a CPAN module is usually the right choice. :-)

    Unless the programmer actually read the spec. From the OP "i.e. 1 char from each string until the 2nd string (which will be always shorter)".

    Had that not been specified, or if you'd read on a little, you'd have found Re^3: Merge 2 strings like a zip [benchmark] which contains:

    sub zipD($$) { my( $a, $b ) = length( $_[0] ) < length( $_[1] ) ? @_[ 1, 0 ] : @ +_[ 0, 1 ]; substr( $a, $_*2+1, 0, substr( $b, $_, 1 ) ) for 0 .. length( $b ) + -1; return $a; }

    BTW, if you think all the code on CPAN is correct, you have a very rude awaking coming.

    And if you feel you'll never be a better programmer than the average on CPAN; keep on using it, instead of your own brain; and you'll be right.
