Note

The machine is stateless and can be reused for multiple evaluations. All the state is expected to be in the budgetSpender and logger implementations.

Example

 val term = LamAbs("x", Apply(Var(NamedDeBruijn("x", 0)), Var(NamedDeBruijn("x", 0))))
 val cek = new CekMachine(MachineParams.defaultParams, NoBudgetSpender, NoLogger, JVMPlatformSpecific)
 val res = cek.runCek(term)
