… x (design sketch) A parenthesized bare name whose final segment starts lowercase is by convention a value, not a class, so a cast mis-parse of the ambiguous shapes is rebuilt in AstBuilder as the binary expression the syntax visually suggests, preserving textual left-to-right grouping across precedence levels. The binary-only keywords in/as captured as cast operand identifiers are restored to their relational reading for any capitalization. Unresolvable bare-name cast types now carry a hint explaining the ambiguity and the ((name)) workaround. The grammar is unchanged: a predicate-gated castExprAlt is not viable because adaptive prediction under the me.sunlan antlr4 fork only consults semantic predicates when a decision conflict is registered, which this decision never produces, so the predicate would only fire as a parse-time FailedPredicateException. -- This is an automated message from the Apache Git Service.
