my $E = binary($k);
I said $E will be assigned the string that represents $k, not it's
value.

Hi,
I was reading Higher Order Perl[1] last night and, dishearteningly,
got stuck on chapter one.
Mark Dominus offers the following as a binary string conversion
example of how recursion can work.
use strict;
use warnings;
my $bstr = binary(37);
print "$bstr\n"; # prints 10010
