.recursive_build(buildee, props, prototype = nil) ⇒ <Ryo::Object, Ryo::BasicObject>

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Note:

When "props" is given as a Ryo object, a duplicate Ryo object is returned in its place

Creates a Ryo object by recursively walking a Hash object, or an Array of Hash objects

Examples:

objects = Ryo.from([{x: 0, y: 0}, "foo", {point: {x: 0, y: 0}}])
objects[0].x       # => 0
objects[1]         # => "foo"
objects[2].point.x # => 0

Parameters:
