The problem with "Choice" with complex components (like your sequences),
is that all choices must attempted.  When all fail, each block can have
a different reason why it fails.

Add this to the top of your script, to get some extra debug information:

  use Log::Report mode => 'DEBUG';   # or:    mode => 3

and you would probably have seen this problem.  I am putting some extra
"trace" messages in the compilation and run-time, as long as they do not
delay the normal message processing.  Suggestions welcome.
