Code​:
*(42)

Result​:
Cannot find method 'CALL-ME'
  in block <unit> at -e line 1

This error message is not very user friendly.

Relevant piece of IRC log​:

<lizmat> perhaps Whatever and HyperWhatever need a CALL-ME with a better
error message
<jnthn> I don't like adding methods just to report errors
<jnthn> Breaks introspection
<jnthn> Any smarts want to go into X​::Method​::NotFound.

Tagging testneeded

The RT System itself - Status changed from 'new' to 'open'

From @usev6

This fails now with X​::Method​::NotFound and the error message has some more informations​:

$ perl6-m -e '*(42)'
No such method 'CALL-ME' for invocant of type 'Whatever'
  in block <unit> at -e line 1

I added a simple test to S02-types/whatever.t with commit Raku/roast@f90f4e371b .

I'm closing this ticket as 'resolved'.
