Following up on my earlier thread, I've released a working version
(bleeding edge, early alpha) of 'eptl', my block-syntax extension to PTL.

I've written a few small applications with it. Personally, I'm happy
with the syntax, and plan to keep using it. :-) If you're crazy enough
to try it out, I'd love to hear your feedback.

Requires a slightly-patched Quixote, or the unreleased Quixote 2.2. See
the page for details.
