[antlr-interest] shorthand for sequence of same tokens, e.g., A A A A A A

Hi again,

is there a way to abbreviate the definition of rule like the following?

Unicode_escape_sequence:
  | '\\u' HEX_DIGIT HEX_DIGIT HEX_DIGIT HEX_DIGIT;

It would be great to say something like that:

Unicode_escape_sequence:
  | '\\u' HEX_DIGIT{4};

Regards,
Christian
