Subject: Documentation for `seq-contains-p` is outdated
Date: Sat, 15 Aug 2020 16:14:19 +0200 [thread overview]

Hi,
When looking up the documentation for `seq-contains-p` it seems
outdated.
M-x elisp-index-search RET seq-contains-p RET returns:
-- Function: seq-contains-p sequence elt &optional function
This function returns non-‘nil’ if at least one element in SEQUENCE
is equal to ELT. If the optional argument FUNCTION is non-‘nil’,
it is a function of two arguments to use instead of the default
‘equal’.
(seq-contains '(symbol1 symbol2) 'symbol1)
⇒ symbol1
(seq-contains '(symbol1 symbol2) 'symbol3)
⇒ nil
The title is correct but the information shown is for the obsolete
`seq-contains` function.
Best regards,
Iwan in ’t Groen
