Using ==, strings and numbers can compare as equal, and using index()
on a list, this is not the case:
:echo "2" == 2 " Returns 1
:echo index( [ 2 ], "2") " Returns -1
The docs just say that index() will "Return the lowest index in |List|
{list} where the item has a value equal to {expr}", leading one to
assume that equality is checked in the same way as ==, but looking at
the source, we're using a function that "Compares the items just like
"==" would compare them, but strings and numbers are different". So,
is this a behavioral bug, or should the help just make a note that
strings and numbers will not be considered equal?
