That was true for TLUV - iirc "FALSE FALSE 0 TLUV" would preserve the spk =
- but I don't think it's true for OP_FLU: you can't commit to preserving th=
e current script without a way to observe the current script; trying to inc=
lude a copy of the script in the script makes the script size infinite, and=
trying to include a hash of the script inside the script is cryptographica=
lly infeasible=2E
You could just special case "0 0 OP_FLU" to result in the same script rath=
er than an empty one though, which would avoid the need for a dedicated FWD=
_SELF opcode=2E
(Not convinced calling things Jets when they're unrelated to simplicity ma=
kes sense)
