My 2c on this.

I am the maintainer of JimTcl (and I agree it is too big to be considered a candidate).
LIL source code has almost zero comments, poor error checking and no test suite.
I would be very hesitant to adopt it in u-boot without serious work.

I would much rather see effort put into updating hush to upstream.
My guess is that Denys would be amenable to small changes to make it easier to synchronise
with busybox in the future.

Cheers,
Steve
