I'm writing a recursive decent parser for a language called c- for a
school project. Is it OK to merge two or more EBNF rules into one rule
(to reduce the number of functions)? This question looks (a little bit
| very) dumb but I wonder if it causes some kind of associativity
problem or something.


For example,
2. declaration-list->{declaration}+
3. declaration->var-declaration | fun-declaration


declaration-list->{var-declaration | fun-declaration}+


Thank you in advance.
