in reply to length() and the Schwartzian transform

It seems to me that the point of the example is to show how ST works as simply as possible, NOT to show its speed or lack thereof ...

    My main issue with that example is not that it's slow, but that it's misleading. For string scalars, Perl's length returns a value that has already been calculated (and cached) elsewhere. It's just a dumb "accessor method" for that internally stored value, which makes caching it pointless.
