From @usev6

The error message matches that of STD now​:

$ perl6-m -e 'my \foo'
===SORRY!=== Error while compiling -e
Term definition requires an initializer
at -e​:1
------> my \foo⏏<EOL>
  expecting any of​:
  scoped declarator

I added a test to S32-exceptions/misc.t with the following commit​: Raku/roast@67583ed445

@usev6 - Status changed from 'new' to 'resolved'
