Summary : Perl pragma to declare constants
URL : https://metacpan.org/release/constant
License : GPL+ or Artistic
Description : This pragma allows you to declare constants at compile-time:
:
: use constant PI => 4 * atan2(1, 1);
:
: When you declare a constant such as "PI" using the method shown above,
: each machine your script runs upon can have as many digits of accuracy
: as it can use. Also, your program will be easier to read, more likely
: to be maintained (and maintained correctly), and far less likely to
: send a space probe to the wrong planet because nobody noticed the one
: equation in which you wrote 3.14195.
:
: When a constant is used in an expression, Perl replaces it with its
: value at compile time, and may then optimize the expression further.
: In particular, any code in an "if (CONSTANT)" block will be optimized
: away if the constant is false.
