+ * From a formal parameters description and a map of arguments, construct an
+ * arguments array.
+ *
+ * That is, given:
+ * - an LLSD array of length n containing parameter-name strings,
+ *   corresponding to the arguments of a function of interest
+ * - an LLSD collection specifying default parameter values, either:
+ *   - an LLSD array of length m <= n, matching the rightmost m params, or
+ *   - an LLSD map explicitly stating default name=value pairs
+ * - an LLSD map of parameter names and actual values for a particular
+ *   function call
+ * construct an LLSD array of actual argument values for this function call.
+ *
+ * The parameter-names array and the defaults collection describe the function
+ * being called. The map might vary with every call, providing argument values
+ * for the described parameters.
+ *
+ * The array of parameter names must match the number of parameters expected
+ * by the function of interest.
+ *
+ * If you pass a map of default parameter values, it provides default values
+ * as you might expect. It is an error to specify a default value for a name
+ * not listed in the parameters array.
+ *
+ * If you pass an array of default parameter values, it is mapped to the
+ * rightmost m of the n parameter names. It is an error if the default-values
+ * array is longer than the parameter-names array. Consider the following
+ * parameter names: ["a", "b", "c", "d"].
+ *
+ * - An empty array of default values (or an isUndefined() value) asserts that
+ *   every one of the above parameter names is required.
+ * - An array of four default values [1, 2, 3, 4] asserts that every one of
+ *   the above parameters is optional. If the current parameter map is empty,
+ *   they will be passed to the function as [1, 2, 3, 4].
+ * - An array of two default values [11, 12] asserts that parameters "a" and
+ *   "b" are required, while "c" and "d" are optional, having default values
+ *   "c"=11 and "d"=12.
+ *
+ * The arguments array is constructed as follows:
+ *
+ * - Arguments-map keys not found in the parameter-names array are ignored.
+ * - Entries from the map provide values for an improper subset of the
+ *   parameters named in the parameter-names array. This results in a
+ *   tentative values array with "holes." (size of map) + (number of holes) =
+ *   (size of names array)
+ * - Holes are filled with the default values.
+ * - Any remaining holes constitute an error.
