perl6-debug-m Regex and Grammar Debugging
Message ID:

I'm trying to use perl6-debug-m for doing Regex and Grammar Debugging. 

When I use Rakudo version 2016.10 , it's works fine. I get the behaviour which is described at in section "Regex and Grammar Debugging". I can easily see how the regex/grammar expressions are evaluated. This is a great help. 

When I use with Rakudo version 2017.07 (I also tried with Rakudo version 2018.01), it doesn't work as expected. The perl6 debugger doesn't show anything about the regex/grammar evaluation. 

I use the same perl6 program for testing. The only difference I see is the perl6 version. 

Trace in Rakudo version 2017.07 (not working as I expect) 

Trace in Rakudo version 2016.10 (working as I expect) 

Do you have any explanation ? Is it a bug or I miss something ? 

Thanks a lot for your help.
