Using prg on a high-volume site is discouraged, as all requests will be 
fed through a single instance of the prg, creating a significant 
bottleneck. The dash2under.pl example is just that - an example - and 
there are better ways to accomplish what it does ... as there are, 
usually, better ways to accomplish things that prg can be used for.

Consider mod_lua as an alternative way to do rewritemap-ish things
