In the code generated for the following rule, the
VarSpecContext.expressionList() method returns a
List<TerminalNode<Token>> when in reality the expressionList rule
can be called at most 1 time.

varSpec
: identifierList
( type ('=' expressionList)?
| '=' expressionList
)
;

I think this has to do with the fact that both occurrences of expressionList appear in the same outer alternative of the rule even though at most 1 lies on a path from rule start to stop.
