I'm not sure exactly what you're going for, but maybe this helps:

Win8 Strawberry 5.8.9.5 (32) Sun 11/22/2020 1:19:09 C:\@Work\Perl\monks >perl use strict; use warnings; use constant INVALID_DATA => ( q{invalid}, 0 ); use constant ADD_DATA => ( q{add}, 1 ); use constant REMOVE_DATA => ( q{remove}, 2 ); use constant MODES => ( \&ADD_DATA, \&REMOVE_DATA ); warn((ADD_DATA)[0]); warn((ADD_DATA)[1]); warn((MODES)[0]); warn((MODES)[1]); warn((MODES)[0]->()); warn((MODES)[1]->()); ^Z add at - line 11. 1 at - line 12. CODE(0x1d2be34) at - line 14. CODE(0x1cf904c) at - line 15. add1 at - line 17. remove2 at - line 18.
(Update: Also works under Perl version 5.30.3.1 64-bit.)

Update 1: Changed example code above: removed unused use Data::Dumper; statement.

Update 2: The syntax &{(MODES)[0]} also works, and you may consider it more elegant:

Win8 Strawberry 5.8.9.5 (32) Sun 11/22/2020 1:34:08 C:\@Work\Perl\monks >perl use strict; use warnings; use constant ADD_DATA => qw(add 1); use constant REMOVE_DATA => qw(remove 2); use constant MODES => (\&ADD_DATA, \&REMOVE_DATA); warn &{(MODES)[0]}; warn &{(MODES)[1]}; ^Z add1 at - line 8. remove2 at - line 9.
Also works under version 5.30.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
