An SLR parser generator written in Gofer (a Haskell variant) by Torben AEgidius Mogensen . Ratatosk generates purely functionalbacktracking {LR0 grammar} {parser}s (also in Gofer). Even though the sematic value of a production is a function of the attributes of its right-hand side (and thus apparently purely synthesised), inherited attributes are easily simulated by using higher-order functions. .
