Extra argument for list accessors
Posted: Sat Apr 21, 2007 9:23 pm
I was thinking that it might be nice to add an extra optional argument at the end of the functions FIRST, LAST, NTH, REST and SLICE that represent a value that is to be substituted at that position. So for example
(first "cat") -> "c"
(first "cat" "b") -> "bat"
or
(nth 2 '(2 3 7 77 8) 6) -> '(2 3 6 77 8)
and so on.
(first "cat") -> "c"
(first "cat" "b") -> "bat"
or
(nth 2 '(2 3 7 77 8) 6) -> '(2 3 6 77 8)
and so on.
