oaklisp 1.3.7-2 (amd64 binary) in ubuntu eoan

 Oaklisp is a dialect of Scheme that combines lexical scoping with
 first-class types. It uses a byte-coded implementation, but is
 reasonably fast anyway. Complete with bignums, formatted output,
 transparent delays, RnRS compatibility package; all the luxuries
 except floating point and foreign function calls.
