What you're saying isn't correct, Eli. That period you are pointing to
has _exactly_ the same magic "elsewhere in Lisp" as it does in "pcase".
Forget pcase for a minute. "Elsewhere in Lisp", if all those 5 symbols
are bound, then your example (now corrected):
`(,hookfun . (,start ,end ,collection . ,plist))
produces a list made up with four cons cells.
If you take out the periods:
`(,hookfun (,start ,end ,collection ,plist))
This still produces a list, but now it's made up of six cons cells!
That's a world of difference.
In a different email, I've explained how, both in 'pcase' and "elsewhere
in Lisp", your example can be rewritten with one less period to still use
four cons cells exactly.
