The following module was proposed for inclusion in the Module List:
modid: Constant::
DSLIP: bdprp
description: Create read-only scalars, arrays, hashes.
userid: ROODE (Eric J. Roode)
chapterid: 2 (Perl_Core_Modules)
communities:
RPI lily server
similar:
"use constant" pragma
rationale:
Perl's built-in pragma creates only scalars and lists, creates
variables that have no leading $ character, and which cannot be
interpolated into strings. Also, it works only at compile time.
Constant.pm, on the other hand, will work with global variables and
with lexical ("my") variables. It will create scalars, arrays, or
hashes, all of which look and work like normal, non-constant Perl
variables.
Constant.pm uses tied variables, so it has a performance penalty as
compared to "use constant", but I believe it makes a valuable
complement to the pragma.
