Method: Hash#rekey!

Defined in:
lib/core/facets/hash/rekey.rb

#rekey!(key_map = nil, &block) ⇒ Object

Synonym for Hash#rekey, but modifies the receiver in place (and returns it).

foo = { :name=>'Gavin', :wife=>:Lisa }
foo.rekey!{ |k| k.to_s }  #=>  { "name"=>"Gavin", "wife"=>:Lisa }
foo                       #=>  { "name"=>"Gavin", "wife"=>:Lisa }
