[EP] Support dash in identifier?

Enhancement

do we need to support dash in identifier?

e.g.,

api-Version = "apps/v1"

related issue: #1787

I support this if modules are also updated to support dashes for consistency. Otherwise we have a situation where my-app = {} is valid but import .my-app and my-app.Schema{} is not.

I personally think that the semantic distinction between fields and identifiers is enough to explain the issue in #1787. Wrapping the top level in {} to turn it into a single dict export to allow string-literals as fields makes sense.

My motivation for semi-supporting the change is to align module naming with that of file/directory naming and by extension, that would include supporting the dash in identifiers.
