445 remprop
:start indicates the start position for the operation within the sequence.
:end indicates the position of the first element in the sequence beyond the
end of the operation. It defaults to nil (the length of the sequence).
If both :start and :end are omitted, the entire sequence is processed by
default.
For example:
(remove-if-not #'atom '('a 1 "list")) => (1 "list")
(remove-if-not #'numberp '('a 'b 'c) :start 1 :end 2) => ('A 'e)
(remove-if-not #'evenp '(1 235) :start B :end 3) => (2 5)
The :count argument, if supplied, limits the number of elements deleted.
If more than :count elements of sequence satisfy the predicate, then only
the leftmost :count of those elements are deleted.
For example:
(remove-if-not #'oddp '(1 1 2 2) :count 1 ) => (1 1 2)
remove-if-not is the non-destructive version of delete-if-not.

remprop symbol indicator Function
The remprop function removes from the property list in symbol a property
with an indicator eq to indicator. For example, if the property list of foo
was:
then:
(color blue height six-three near-to bar)
(remprop 'faa 'height) => (six-three near-to bar)
and foo's property list would be:
