How are you using Babel?

Programmatic API (babel.transform, babel.parse)

Input code

I ran into this while fixing #14123, and the fix for that will include a fix for this too. If you try the following code:

require("@babel/parser").parse("import * from 'pizza'", { sourceType: "module" });

See it here: https://runkit.com/tolmasky/expectcontextual-drops-token-information

You'll get SyntaxError: Unexpected token (1:9), despite the code having enough information to say "Unexpected token, expect "as"", and in fact it appears like it was originally designed to do so. However, this information is lost between the conversion from expectContextual and unexpected.
