compile/declare-exports

Syntax: (declare-exports NAME ...)

Behaviour: Expands to (define-global __features__ #(...)) holding the sorted, deduplicated names as strings. Each name is a feature stem. When the module finishes loading, __all__ is built from the stems as the bindings that exist: the runtime name and its compile/ and layout/ facets. A Python-side star import therefore sees only what is bound, while use and import-all-from carry every facet of a feature. A name written with a facet prefix exports that one binding.

Examples:

;; shapes.ki
(declare-exports area define-shape)

def area [w h] (* w h)

syntax define-shape:
  ...

>>> (declare-exports greet shout)
>>> __features__
#("greet" "shout")
