Method skip

packages/compiler/src/expression_parser/parser.ts:1867–1891

* Error recovery should skip tokens until it encounters a recovery point. * * The following are treated as unconditional recovery points: * - end of input * - ';' (parseChain() is always the root production, and it expects a ';') * - '|' (since pipes may be chained and each pipe

()

   * and then decrements it just prior to checking if the token is in the input.
