if

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.
