(This is done via an Object.seal(this) call after a newly +// created instance defines its own properties according to the descriptor +// on its constructor class.) +// +// 2) Properties may have two flags set: update and expose. Properties which +// update are provided values from the external. Properties which expose +// provide values to the external, generally dependent on other update +// properties (within the same object). +// +// 2a) Properties may be flagged as both updating and exposing. This is so +// that the same name may be used for both "output" and "input". +// +// 3) Exposed properties have values which are computations dependent on other +// properties, as described by a `compute` function on the descriptor. +// Depended-upon properties are explicitly listed on the descriptor next to +// this function, and are only provided as arguments to the function once +// listed. +// +// 3a) An exposed property may depend only upon updating properties, not other +// exposed properties (within the same object). This is to force the +// general complexity of a single object to be fairly simple: inputs +// directly determine outputs, with the only in-between step being the +// `compute` function, no multiple-layer dependencies. Note that this is +// only true within a given object - externally, values provided to one +// object's `update` may be (and regularly are) the exposed values of +// another object. +// +// 3b) If a property both updates and exposes, it is automatically regarded as +// a dependancy. (That is, its exposed value will depend on the value it is +// updated with.) Rather than a required `compute` function, these have an +// optional `transform` function, which takes the update value as its first +// argument and then the usual key-value dependencies as its second. If no +// `transform` function is provided, the expose value is the same as the +// update value. +// +// 4) Exposed properties are cached; that is, if no depended-upon properties are +// updated, the value of an exposed property is not recomputed. +// +// 4a) The cache for an exposed property is invalidated as soon as any of its +// dependencies are updated, but the cache itself is lazy: the exposed +// value will not be recomputed until it is again accessed. (Likewise, an +// exposed value won't be computed for the first time until it is first +// accessed.) +// +// 5) Updating a property may optionally apply validation checks before passing, +// declared by a `validate` function on the `update` block. This function +// should either throw an error (e.g. TypeError) or return false if the value +// is invalid. +// +// 6) Objects do not expect all updating properties to be provided at once. +// Incomplete objects are deliberately supported and enabled. +// +// 6a) The default value for every updating property is null; undefined is not +// accepted as a property value under any circumstances (it always errors). +// However, this default may be overridden by specifying a `default` value +// on a property's `update` block. (This value will be checked against +// the property's validate function.) Note that a property may always be +// updated to null, even if the default is non-null. (Null always bypasses +// the validate check.) +// +// 6b) It's required by the external consumer of an object to determine whether +// or not the object is ready for use (within the larger program).
