+
+This API varies from Tyler Closes ref_send in the
+following ways:
+
+*   Promises can be resolved to function values.
+*   Promises can be resolved to null or undefined.
+*   Promises are distinguishable from arbitrary functions.
+*   The promise API is abstracted with a Promise constructor
+    that accepts a descriptor that receives all of the
+    messages forwarded to that promise and handles the
+    common patterns for message receivers.  The promise
+    constructor also takes optional fallback and valueOf
+    methods which handle the cases for missing handlers on
+    the descriptor (rejection by default) and the valueOf
+    call (which returns the promise itself by default)
+*   near(ref) has been changed to Promise.valueOf() in
+    keeping with JavaScript's existing Object.valueOf().
+*   post(promise, name, args) has been altered to a variadic
+    post(promise, name ...args)
+*   variadic arguments are used internally where
+    applicable. However, I have not altered the Q.post()
+    API to expand variadic arguments since Tyler Close
+    informed the CommonJS list that it would restrict
+    usage patterns for web_send, posting arbitrary JSON
+    objects as the "arguments" over HTTP.
