# Refinement for extending JSON with #deep_parse functionality

# Valid JSON can only map to a fixed set of objects in Ruby so we
# can easily define a solution for each potential value of a valid
# JSON object while attempting to reparse any strings that are found
# that may be potentially deeply escaped JSON.
