Complex parametric role composition fails badly when no candidate found #4513
Comments
From @dakkarThis code:: role R[$a,$b] {} C.new; Produces the error message:: ===SORRY!=== The error happens in ``RoleToClassApplier::apply``: something goes -- Giving up on assembly language was the apple in our Garden of Eden: |
From @lizmatOne would expect an error message such as: $ 6 'role R[$a,$b] {}; class C does R[1] {}' but even that message is rather LTA, as it doesn’t mention which parameters were tried and which candidates are available. Liz

The current error message looks good to me:
Should probably got a test in Rakudo's test suite. |
Migrated from rt.perl.org#125996 (status was 'open')
