This is more artifice than obfuscation.

The "& _ x ord $ ;" code is used to convert my lowercase PerlMonks ID jmcnamara to my uppercase CPAN directory JMCNAMARA. I could have used uc but I thought that I should put in a little effort. ;-)

# The following are equivalent perl -MCPAN -e 'install jmcnamara & _ x ord $ ;' perl -MCPAN -e 'install "jmcnamara" & ( "_" x ord($;) )' perl -MCPAN -e 'install "jmcnamara" & ( "_" x 28 )' # With bitwise string "&" the longer string is truncated # to the length of the shorter string. Therefore: perl -MCPAN -e 'install "jmcnamara" & ( "_" x 9 )' perl -MCPAN -e 'install "jmcnamara" & "_________"' perl -MCPAN -e 'install JMCNAMARA'

Running this will cause CPAN to generate an error because you are trying to install a directory instead of module (or bundle). This helpfully translates my PerlMonks name into my real name. Here is the output as seen through tail -l.     Don't be silly, you can't install John McNamara ;-)

This error message is buried in CPAN.pm.
