| Aug 3, 2017 at 9:52 | comment | added | Nagev | I still prefer this answer because it works out-of-the-box and in my opinion, still very simple. Just to add that enumeration would normally use integers to represent the different values, e.g. HOME => 0. I wouldn't use strings unless I need to actually print the names. | |

| Jan 19, 2010 at 11:36 | comment | added | Ronald Blaschke | Your examples don't match up ;-), but yes, the current implementation does. See section TECHNICAL NOTES in perldoc constant. constant also does some name checking. For example, starting with double underscores is disallowed, and names like 'BEGIN' cause a warning (with 'use warnings') because they might be confusing. For details have a look at the implementation by calling 'perldoc -m constant'. | |
| Jan 18, 2010 at 18:18 | comment | added | Phill Pafford | Just for clarification sub HOME () {'home'} and use constant { HOME => 'Home', WORK => 'Work', MOBILE => 'Mobile', }; are the same? the later generates (Behind the scene) the code? | |
| Jun 25, 2009 at 10:13 | comment | added | Cheok Yan Cheng | When you have a subroutine which take in Phone::Type enum as argument, how do you perform dynamic checking on the subroutine argument is Phone::Type type enum, not string, not number... | |

Added prototype to sub HOME (many thanks to Hynek -Pichi- Vychodil for mentioning this)
