#with_nested_access! ⇒ Object

Allow any level of access by providing a default value at each level.

Examples

Hash without nested access (or any given defaults)

h = Hash.new h # => nil h[:c] # => NoMethodError: undefined method `[]' for nil:NilClass

h.with_nested_access!
h[:b]          # => {}
h[:b][:c]      # => {}
h[:b][:c][:d]  # => {}
