Method: Hash#deep_dup

Defined in:
lib/sc-core-ext/hash.rb

#deep_dup ⇒ Object

Performs a “deep copy” of this hash; that is, returns a Hash that is a duplicate of this Hash, and whose keys and values have each, in turn, had #deep_dup or #dup called on them. This should produce a Hash whose every element is a copy of the original.

This operation is expensive, and should be used sparingly.
