Can't you just use the -e switch?

perl -e 'use Socket; ($a, $b, $c, $d) = unpack("C4", gethostbyname("www.foo.com")); print "$a.$b.$c.$d\n";'


If this isn't what you want, maybe I'm not understanding your question properly...

By the way, you don't have to embed the name inside the command.  You can still use $ARGV[0] and then place the hostname on the command line after the execution string:

perl -e 'use Socket; ($a, $b, $c, $d) = unpack("C4", gethostbyname($ARGV[0])); print "$a.$b.$c.$d\n";' www.foo.com


Hope this is what you need...
