Instance Method Detail
Check if the current token matches the given type and return truthy if it does. Additionally, if the type matches, automatically advance to the next significant token.
Advance through the token stream until a significant token is encountered. This abstraction allows the rest of the parser to quietly ignore whitespace and other insignificant tokens.
Similar to #accept, but raise an error if the type does not match.
The list of instructions parsed from the source code. This is what will be fed to the interpreter.
