NAME

if - "use" a Perl module if a condition holds

  use if CONDITION, MODULE => ARGUMENTS;

The construct

  use if CONDITION, MODULE => ARGUMENTS;

has no effect unless "CONDITION" is true. In this case the effect is the same as of

  use MODULE ARGUMENTS;

Above "=>" provides necessary quoting of "MODULE". If not used (e.g., no ARGUMENTS to give), you'd better quote "MODULE" yourselves.

The current implementation does not allow specification of the required version of the module.
