Has anyone seen this before? This grammar gives the same error:
Tokens
comma = ',';
Productions
script = paren_args? {-> New script() };
paren_args {-> node* } = opt_call {-> [opt_call.node] };
call_args {-> node* } = opt_call {-> [opt_call.node] };
opt_call {-> node? } = {-> Null };
Abstract Syntax Tree
script = ;
node = ;
I'm using sablecc-3.2
