Recall that Jeff is a statically-scoped language. Assume a new variant of Jeff, called Jeff', that uses the exact same syntax as Jeff but is dynamically-scoped. Provide an input file that would be valid in both Jeff or Jeff', but prints a different result based on which scoping system is used. Show what the output would be either under scheme.
Provide an input file that would be valid in Jeff', but not in Jeff.
Explain the difference between an SLR and an LR(0) parser. Provide an example grammar that is SLR-parseable but not LR(0) parseable.
