Test for some context issue

[AlexDaniel]

When trying some older camelia queries I found this:

Code:

sub plop { loop (my int $i = 0; $i < 10; ++$i) { say $i }; }; plop();

Result (2015.12):

No lexical found with name '$i'
in block <unit> at /tmp/sNWgnSu4JV line 1

Result (HEAD):

0
1
2
3
4
5
6
7
8
9

Bisectable says that it was fixed in rakudo/rakudo@37e742f

I wonder if there's any test for this. If not, then we should probably add one.
