Fixed Point

Fixed point combinators, for helping with recursion. Several formulations are provided, but stick to fix (should be the most efficient at any given time, and thus somewhat more future-proof).

Compose

Compose functions to do convenient partial applications. Versions for composing left-to-right and right-to-left are provided, but the operator <|> is done "the math way" (right-to-left). Versions on lists also available.

Sequence

Really here for pred and succ on integers, by why stop there? This works with any ordered collection.

Curry

Functions

curry creates a 0-arity function that curries an existing function. uncurry applies arguments to curried functions, or if passed a function creates a function on pairs.

Macros

Why define the function before currying it? defcurry and defcurryp return fully-curried 0-arity functions.

Partial

:crown: We think that this is really the crowning jewel of Quark. defpartial and defpartialp create all arities possible for the defined function, bare, partially applied, and fully curried. This does use up all the full arity-space for that function name, however.

Closing Remarks

We hope that you enjoy Quark! Please let us know if you have new feature requests.
