"5r" is neither a bareword nor a correct number. See

  http://www.perl.com/pub/a/2001/01/begperl6.html

for the definition of "bareword".

It is the same reason why my sig does not produce an error. :-)
The bareword "r5" is taken as a string. Use "use strict" or "use warning"
to get an error or a warning respectively.

Mikhael.
