Good morning,

> Could anyone propose a better use case of CODESEPARATOR?

Long ago, aj sent an email on Lightning-dev about use of CODESEPARATOR to i=
mpose Scriptless Script even without Schnorr. It involved 3 signatures with=
 different CODESEPARATOR places, and forced R reuse so that the signatures =
to claim the funds revealed the privkey.

The script shown had all CODESEPARATOR in a single branch.

I cannot claim to understand the script, and am having difficulty digging t=
hrough the mailinglist

Regards,
ZmnSCPxj
