But aren't 'locals' actually PICK/ROLL in disguise?

Do PICK/ROLL skim all the values off the stack and stuff them in
variables to be later popped on and off the stack like a yo-yo?

 
Locals can be (and I thought usually are) implemented with the
equivalent of PICK and POST, on either the R stack or a separate L
stack.  ROLL is different, "n ROLL" actually shuffles n items around and
in most situations seems kind of nuts.

PICK copies a stack item.  Agree it and ROLL have limited use.  OTOH
SwiftForth has -ROLL and it was recently added to Mecrisp-Stellaris.
What is POST ?
