Why are expressions allowed at the top level? #104

Why is expression_item allowed to appear directly at the top level / in a structure? I might not be thinking of an edge case but ordinarily expressions should appear under value definitions.

OCaml allows top level expressions. It's not considered to be a good practice, but it's valid code, so tree-sitter-ocaml has to parse it.
