I'm looking for a toy imperative language implementation in Haskell for research purposes. I imagine something like the language of arithmetic expressions from TAPL ch. 3 augmented with
- while-loop (so the CFG has loops)
- blocks (sequence of statements to put inside loops and conditionals)
- assignment (otherwise we can't show any effects from sequences)
I think there's probably nothing exactly like that so we might end up doing it ourselves but maybe there's already something out there.
Thank you in advance.
Regards,
