Disciple is an explicitly lazy dialect of the functional programming language Haskell.
Disciple vs Haskell
* Strict EvaluationOrder is the default, laziness is introduced explicitly. * All data objects support DestructiveUpdate, without the need for Ref types. * Type directed FieldProjections complement type classing. * Supports a try-catch ExceptionMechanism. * The TypeSystem ensures that SideEffects and DestructiveUpdate play nicely with laziness.
Some example code, and it's output.
The Disciplined Disciple Compiler (DDC)
* Uses a typed core language which includes effect, closure, region and mutability information. (example) * This extended type information is used to allow code-transformation style optimizations in the presence of side effects and mutable objects. * Produces standard C99, so is highly portable. * Is in a usable alpha state.
