+    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. In this case, the pragma will always be considered to

+    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.
