great!

although i must note that it has no direct effect on me currently, so
don't fall in the trap of too early, too much and unprofiled
optimization...

the only reason i've touched that part of the code is the iter
dependency, which is arguable anyway. we like and use iter more than
loop, but it's at the bottom of our TODO to write an iter lib using a
proper walker and properly updating the lexenv...

we have several transitive cl-ppcre dependencies, and all our own
usages are in non-performance-critical code, so for now we don't bring
in cl-irregsexp as a +1 dep.
