Introduction of the ERROR symbol is an ugly hack. There's no reason to special case large integer values, the NUM token only exists for small values that are needed immediately, everything else is passed as EXPR_SYMBOL to evaluation anyways. Additionally the error reporting is different from what we'd usually report, the token is easy to confuse with the bison internal error token and it even has a name, messing up bison internal diagnostics. Simply return values to large to be handled by strtoull as STRING.
