Beyond obfuscation, I can only think of one reason to write something

it doesn't validate anything.

And the only thing that is untainted is the last digit found in the
target string, as found in $1. The target string itself is still as
tainted as ever.

I like the obfuscation theory. Either for its own sake, or as part of
some challenge or exercise.
