-// ## Token types
-
-// The assignment of fine-grained, information-carrying type objects
-// allows the tokenizer to store the information it has about a
-// token in a way that is very cheap for the parser to look up.
-
-// All token type variables start with an underscore, to make them
-// easy to recognize.
-
-// The `beforeExpr` property is used to disambiguate between regular
-// expressions and divisions. It is set on all token types that can
-// be followed by an expression (thus, a slash after them would be a
-// regular expression).
-//
-// `isLoop` marks a keyword as starting a loop, which is important
-// to know when parsing a label, in order to allow or disallow
-// continue jumps to that label.
-
