Instance Public methods
Sets the default value, the value returned for a key that does not exist in
the hash. It is not possible to set the default to a Proc that
will be executed on each key lookup.
h = { "a" => 100, "b" => 200 }
h.default = "Go fish"
h["a"] #=> 100
h["z"] #=> "Go fish"
# This doesn't do what you might hope...
h.default = proc do |hash, key|
hash[key] = key + key
end
h[2] #=> #<Proc:0x401b3948@-:6>
h["cat"] #=> #<Proc:0x401b3948@-:6>
