I occassionally use -s in one-off programs. Once I find myself setting more than 3 vars with -s, I switch over to something more suited to the task - usually Getopt::Long, since I like its flexibility.
At one point I was (ab)using -s so much that I wrote a silly module to parse the variables set by -s. The module is pretty boring; code that used it looked like this:
our ( $foo, $bar ) ; # set on command line
sparse( foo => [ qw( f foo -foo --foo ) ],
bar => [ qw( b bar -bar --bar ) ],
print "foo: $foo\nbar: $bar\n" ;
I've currently got one script that uses that module: the test script for the module.
Fortunately I've found better things to waste my time on these days :)
