[antlr-interest] Lexer for 0.Equals(..)

my lexer does not recognize 0.Equals(..) and reports the error:
required (...)+ loop did not match anything at character 'E'
I understand why but I do not know how to resolve it. Here are the
participating rules in order:
: Decimal_digits DOT Decimal_digits Exponent_part? Real_type_suffix?
| DOT Decimal_digits Exponent_part? Real_type_suffix?
| Decimal_digits Exponent_part Real_type_suffix?
| Decimal_digits Real_type_suffix
DOT : '.';
The lexer tries to match the statement from above with the first branch
in the REAL_LITERAL rule but fails after the DOT. Of course. However,
why doesn't it try to match it with other rules after failing?
Furthermore, how can I resolve the problem?
If you need more information, please let me know.
