NAME

constant::string - Perl pragma to declare constants whose values are their own names

VERSION

version 2026.26

SYNOPSIS

use constant::string qw( FOO BAR BAZ );

print FOO;  # Outputs: FOO
print BAR;  # Outputs: BAR

DESCRIPTION

This pragma allows you to declare compile-time constants without having to explicitly repeat their names as string values. Passing a list of strings to use constant::string creates constant subroutines in the caller's namespace where each constant returns its own name.

It behaves exactly like the core constant pragma under the hood, meaning these are fully optimized, inlined compile-time constants—not regular subroutine calls.

SEE ALSO

  • constant - The core Perl pragma utilized under the hood.
