The scenario is simple: modules A.pm and B.pm both use the statement
declaration form; the former includes the latter. Rakudo dies.

$ cat A.pm
use B;

role A;
$ cat B.pm
role B;
$ perl6 A.pm
Unable to parse role definition at line 3, near ";\n"
in Main (src/gen_setting.pm:1490)

I'd expect the restriction on statement-form declarations to be
per-file. So does STD.pm, it seems.
