| 13 | # Similar to the literal <code>{ _key_ => _value_, ... }</code>. In the first | |
| 14 | # form, keys and values occur in pairs, so there must be an even number of | |
| 15 | # arguments. | |
| 16 | # | |
| 17 | # The second and third form take a single argument which is either an array | |
| 18 | # of key-value pairs or an object convertible to a hash. | |
| 19 | # | |
| 20 | # Hash["a", 100, "b", 200] #=> {"a"=>100, "b"=>200} | |
| 21 | # Hash[ [ ["a", 100], ["b", 200] ] ] #=> {"a"=>100, "b"=>200} | |
| 22 | # Hash["a" => 100, "b" => 200] #=> {"a"=>100, "b"=>200} | |
