[7bf7fb9]39// Difficult to separate extra parts of constants during lexing because actions are not allow in the middle of patterns:
40//
41// prefix action constant action suffix
42//
43// Alternatively, breaking a pattern using BEGIN does not work if the following pattern can be empty:
44//
45// constant BEGIN CONT ...
46// <CONT>(...)? BEGIN 0 ... // possible empty suffix
47//
48// because the CONT rule is NOT triggered if the pattern is empty. Hence, constants are reparsed here to determine their
49// type.
