can follow the progress on the issue there. Let us know if your problem is
actually different.

Hi,

According to the documentation one should use the following to trap a 
failure when loading a module fails using require;

try require ::('Foo');
note ::('Foo').Str if ::('Foo') ~~ Failure;

The problem with this is that it isn't visible what is going wrong. 
Using plain

require ::('Foo');

an exception is thrown with a proper error and stack dump. However when 
there are no errors in the module, there are other exceptions thrown 
with messages like

WARNING: unhandled Failure detected in DESTROY. If you meant to ignore it, you 
can mark it as handled by
  calling .Bool, .so, .not, or .defined methods. The Failure was:
No such symbol 'Foo'
   in block  at ... (...) line ...
...

This seems to me a bug. The only way to handle this properly is the 
following

try {
   require ::('Foo');

   ...

   CATCH {
 .note;
   }
}
