MirBSD manpage: if(3p)
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.
