Internal representation of values: module venture.lite.value

Venture values.

The design currently lives in doc/type-system.md

class venture.lite.value.SPRef(makerNode)

Bases: venture.lite.value.VentureValue

asStackDict(trace=None)
static fromStackDict(thing)
class venture.lite.value.VentureArray(array)

Bases: venture.lite.value.VentureValue

Venture arrays are heterogeneous, with O(1) access and O(n) copy.

class venture.lite.value.VentureArrayUnboxed(array, elt_type)

Bases: venture.lite.value.VentureValue

Venture arrays of unboxed objects are homogeneous, with O(1) access and O(n) copy.

Simplexes are homogeneous unboxed arrays of probabilities. They are also supposed to sum to 1, but we are not checking that.
