Code:
our Str $foo;

Result:
===SORRY!=== Error while compiling /home/alex/perl6test/./test3.pl
Cannot put a type constraint on an 'our'-scoped variable
at /home/alex/perl6test/./test3.pl:2
------> our Str $foo⏏;
    expecting any of:
        constraint

It says “cannot put a type constraint” but then goes “expecting any of:
constraint”.
