No, I just showed these comments from code for quick reference
to explain what the $3 and $5 on the righthand side of a hash lookup
could do.

Yes, considering the righthand side of a lookup: { '.' => '$3.$5' }
and the use of _OPTION_ in an altermime template:

Not easily. One could perhaps use some custom hook hack,
or use some custom shell wrapper around altermime.

It is usual that a MUA when replying strips off a signature from
quoted text.  Signatures are by convention delimited from text
by an '--' line.

Not off-the-shelf. Some hack with a custom hook could so the job.

Right. I said so in my posting.
