In ANTLR, you can have direct left recursive,

expression
   : outerAttribute+ expression                         # AttributedExpression // technical, remove left recursive
   | literalExpression                                  # LiteralExpression_
   | pathExpression                                     # PathExpression_
   | expression '.' pathExprSegment '(' callParams? ')' # MethodCallExpression   // 8.2.10
   | expression '.' identifier                          # FieldExpression  // 8.2.11
   | expression '.' tupleIndex                          # TupleIndexingExpression   // 8.2.7
   ...

which makes it easy to implement any expression with precedence
