Why not exclude the Script grammer target?

Wonder why you appear to allow legacy Scripts when you could say that only the Module top level sematics is supported.

The primary difference between a script and a module with no import/export is implicit strict mode, top level declaration are module scopes, and top level this is undefined. Those all seem like desirable characteristics and having only a single kind of top level code unit seems like a significant simplification.

Hi @allenwb , thanks for the suggestion. This seems like a good idea. Will close once I've revised the text.

The grammar does not yet include export and import. See https://github.com/Agoric/Jessie/issues/8

@allenwb , We've decided to take your suggestion. Once we support modules well in the ses-shim (attn @michaelfig ), we'll be able to close this.

Done.
