We have updated notes for the => operator to make it clear it will *match* keys. We have also updated the functions in the maps module to mention *match* semantics (for example, `maps:from_list/1`). We have also removed examples that use `lists:key*` functions since those use equal. Notes regarding ordering have not been affected by this commit.
A couple trivial fixes in eep-0031. Signed-off-by: Tuncer Ayaz <firstname.lastname@example.org>
