         + Add : Returning an empty list from the mangler skips the wrapping of
                 the current typed lexical declaration.

 DESCRIPTION
-    This module allows you to hook the execution of typed lexicals
+    This pragma allows you to hook the execution of typed lexicals
     declarations ("my Str $x"). In particular, it can be used to
     automatically tie or bless typed lexicals.

 CAVEATS
-    For "perl" to be able to parse "my Str $x", the package "Str" must be
-    defined somewhere, and this even if you use the 'as' option to redirect
-    to another package. It's unlikely to find a workaround, as this happens
-    deep inside the lexer, far from the reach of an extension.
+    For "perl" to be able to parse "my Str $x", you need :
+
+    *   either the "Str" package to be defined ;
+
+    *   or for "Str" to be a constant sub returning a valid defined package.
+
+    Those restrictions apply even if you use the 'as' option to redirect to
+    another package, and are unlikely to find a workaround as this happens
+    deep inside the lexer - far from the reach of an extension.
 
     Only one mangler or prefix can be in use at the same time in a given
