-Deletes all instances of a given element from an array, substring from a string, or key from a hash. Arrays and hashes may also match on regular expressions. For example, `delete(['a','b','c','b'], 'b')` returns ['a','c']; `delete('abracadabra', 'bra')` returns 'acada'. `delete({'a' => 1,'b' => 2,'c' => 3},['b','c'])` returns {'a'=> 1}, `delete(['abf', 'ab', 'ac'], '^ab.*')` returns ['ac']. *Type*: rvalue.
