Item 14. Handle big numbers with bignum

Although Perl tries to hide its underlying architectural details from you, in some cases, such as with the highest (or lowest) number it can represent, it has to let those details leak through. Compilations to 32-bit perl are still common, and their integer range is limited to 32 bits. Try this Perl one-liner:

% perl -le 'print 1234567890123456789012345';
