+`L.pick({p1: l1, ...pls})` creates a lens out of the given object template of
+lenses.  When viewed, an object is created, whose properties are obtained by
+viewing through the lenses of the template.  When set with an object, the
+properties of the object are set to the context via the lenses of the template.
+`undefined` is treated as the equivalent of empty or non-existent in both
+directions.
+
+Note that, when set, `L.pick` simply ignores any properties that the given
+template doesn't mention.  Note that the underlying data structure need not be
