I’m literally copying the chain and writing at the right place with bufcompose, old school.

I imagined that may be the case. It just obviously breaks every time you change anything upstream when doing this.

With students we also use the more garage joining of 2 lists.

Probably a safe way to do things, particularly with the native fluid.buf2list and fluid.list2buf, but is an awkward “domain change” having to just to zl to do some processing before going right back into a buffer~ to carry on the native fluid.stuff~.
