Methods for traversing programs

Synopsis

class DryInterp instr where
- dryInterp :: MonadSupply m => instr '(m, fs) a -> m a
observe_ :: (DryInterp instr, HFunctor instr, MonadSupply m) => (forall a. instr '(m, fs) a -> a -> m ()) -> Program instr fs a -> m a
observe :: (DryInterp instr, HFunctor instr, MonadSupply m) => (forall a. instr '(m, fs) a -> a -> m a) -> Program instr fs a -> m a

Documentation

class DryInterp instr where Source #

Dry (effect-less) interpretation of an instruction. This class is like Interp without the monad parameter, so it cannot have different instances for different monads.

Methods

dryInterp :: MonadSupply m => instr '(m, fs) a -> m a Source #

Dry interpretation of an instruction. This function is like interp except that it interprets in any monad that can supply fresh variables.
