This version has a `.then` but doesn't explode. Is it meant to then?

use v6;
my $foo;
my $promise = Promise.new;
$promise.keep;  # no difference with break

# note i added an "await" here.
$promise.then({
note 41;
$foo.does-not-exist;  # hangs? thread dies? no error message!
note 42;  # never reached!
}).then: { say "hi" };

sleep 5;


And this one explodes, but there's no location shown for where the error occurs:

use v6;
my $foo;
my $promise = Promise.new;
$promise.keep;  # no difference with break

# note i added an "await" here.
await $promise.then({
note 41;
$foo.does-not-exist;  # hangs? thread dies? no error message!
note 42;  # never reached!
});

sleep 5;

Hi,

How did you build your Perl 6?

That version number looks suspicious. You say you're on 2016.11-238-g2f502b4, 
but the current HEAD/nom is 2016.11-226-g1d46004, 12 commits fewer than yours.

The most obvious answer is you're in possession of a time machine and are 
reporting bugs from the future. In which case, would you mind including this 
week's lottery numbers in your reply?

Let us know,
Thank you.

Hi,

Would you be able to provide more info on what OS you're using and any 
special/uncommon configuration it may have?

Hi,

Recently after pulling the newest rakudo/moarvm (2016.11-238-g2f502b4 
built on MoarVM version 2016.11-41-gd2139b5 implementing Perl 6.c) I saw 
errors in my code which compiled ok before. This is difficult to golf 
down because it disappears when used in another context. So better 
explain my way of coding.

The error I get now is

/home/marcel/Languages/Perl6/Projects/mongo-perl6-driver/xt/Sxml/driver-authentication.t
 
..
===SORRY!===
Type 'MongoDB::Server' is not declared
at 
/home/marcel/Languages/Perl6/Projects/mongo-perl6-driver/lib/MongoDB/Client.pm6 
(MongoDB::Client):152
--> my MongoDB::Server⏏ $server .= new(
Malformed my
at 
/home/marcel/Languages/Perl6/Projects/mongo-perl6-driver/lib/MongoDB/Client.pm6 
(MongoDB::Client):152
--> my MongoDB::⏏Server $server .= new(


The module in question has the following at the top

use v6.c;

use MongoDB::Server;
use MongoDB::Database;
use MongoDB::Collection;
use MongoDB::Uri;
use MongoDB::Wire;
use MongoDB::Authenticate::Credential;
use MongoDB;

use BSON::Document;
use Semaphore::ReadersWriters;

#---
unit package MongoDB:auth;

#---
class Client {
...
   my MongoDB::Server $server .= new(
 :client(self), :$server-name, :$loop-time
   );

}


The server class is defined likewise as

use v6.c;

use MongoDB;
use MongoDB::Server::Monitor;
use MongoDB::Server::Socket;
use MongoDB::Authenticate::Credential;
use MongoDB::Authenticate::Scram;

use BSON::Document;
use Semaphore::ReadersWriters;
use Auth::SCRAM;

#---
unit package MongoDB:auth;

#---
class Server { ... }


When e.g. the line 'use MongoDB::Uri' is moved above that of 
MongoDB::Server (in the Client module) another error is returned;

Type 'MongoDB::Uri' is not declared
at 
/home/marcel/Languages/Perl6/Projects/mongo-perl6-driver/lib/MongoDB/Client.pm6 
(MongoDB::Client):99
--> my MongoDB::Uri⏏ $uri-obj .= new(:$!uri);
Malformed my
at 
/home/marcel/Languages/Perl6/Projects/mongo-perl6-driver/lib/MongoDB/Client.pm6 
(MongoDB::Client):99
--> my MongoDB::⏏Uri $uri-obj .= new(:$!uri);


Now I found out that when the 'unit package' line is moved above the use 
statements, the error disappears. Can anyone shed some light over this? 
I know that use statements can be used within package, module and class 
to narrow the scope of definitions but I can't remember anything which 
could explain this behavior.

Thanks,
Marcel
