Aodhnait Étaín 48f47671cd Add minus operator ... Adds "minus" operator, both as a unary negation and a binary subtraction. Refactors Parser::bump to actually return the next token, which is slightly more useful for us. Also changes how Token::len is implemented, and now we return 1 for all tokens that are not listed explicitly.		2021-05-27 17:40:36 +00:00
