+ENVIRONMENT
+ "PERL_INDIRECT_PM_DISABLE"
+ If this environment variable is set to true when the pragma is used for
+ the first time, the XS code won't be loaded and, although the 'indirect'
+ lexical hint will be set to true in the scope of use, the pragma itself
+ won't do anything. This is useful for disabling "indirect" in production
+ environments.
+
+ Note that clearing this variable after "indirect" was loaded has no
+ effect. If you want to reenable the pragma later, you also need to
+ reload it by deleting the 'indirect.pm' entry from %INC.
