![]() |
A sequence that contains all the lookup keys in the hash. Note that not all hashes support this (ask the programmer if a certain hash allows this or not).
![]() | ![]() | ![]() | |

Output:

Since hashes do not define an order for their subvariables in general, the order in which key names are returned can be arbitrary. However, some hashes maintain a meaningful order (ask the programmer if a certain hash does that or not). For example, hashes created with the above {...} syntax preserve the same order as you have specified the subvariables.
