It seems like I should not see that backtrace. There is no such problem
when using !!! and ???.

But it goes even further​:
$ perl6 -e '...; 1'
Stub code executed
  in block <unit> at -e​:1

Actually thrown at​:
  in block <unit> at -e​:1

As you can see, no stacktrace when running it with -e. However, the same
code (...; 1) running from file gives a backtrace.

jnthn and moritz discussed that problem a little bit, check out IRC log​:

This no longer behaves differently in a file version on the command line, both giving​:

Useless use of constant integer 1 in sink context (line 1)
Stub code executed
  in any at /Users/williamcoleda/.rakudobrew/moar-2016.07.1/install/share/perl6/runtime/CORE.setting.moarvm line 1

Marking test needed.
