I type this into the REPL​:

loop (my $i = 10; $i > 0; $i--) { say $i; }

It loops and then crashes​:

10
9
8
7
6
5
4
3
2
1
Type check failed in binding to $value; expected Any but got Mu (Mu)
  in any interactive at src/Perl6/Compiler.nqp line 62

But put it in a file and and it finishes fine. This is Rakudo version
2017.01 built on MoarVM version 2017.01 implementing Perl 6.c.
