Hi guys,

Restarting the thread here.

Links to the previous discussions are here:

Here's a JEP draft, please read and review:

More thorough discussion:

As usual, the current patches are here:

Recent updates:
  * Implemented the slicing of large concat chains (required since indy
can only take 253 dynamic arguments), added a regression test.
  * (Maurizio:) Followed up on bytecode footprint with some stress
tests, see the notes above.

Pending discussion:
  * String concatenation metaprotocol, as outlined by Remi
It would be interesting to try different incarnations of this thing, but
I don't have more time this week.
