if(3p) Perl Programmers Reference Guide if(3p)
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.
