I can confirm that this is still happening as of today's rakudo. It seems like
an important bug to fix, but maybe more importantly, how are we supposed to
handle circular deps? Consider a pair of classes, Tree and Node, which both
need to refer to each other.
Tree.pm6
--------
unit class Tree;
use Node;
has Node $top;

Node.pm6

unit class Node;

Given that I have to use a module in order to refer to its type, this seems
like a problem that will occur _way_ more often in Perl 6 than in Perl 5.
Often you can cope by not typing them in both modules . Then e.g. the
node create method in the Tree module creates the Node object which
receives the Tree object via the BUILD method. The Node module then does
not have to import the tree module because all information is included
in the Tree object just received. So the 'use Tree;' in Node.pm is not
needed.
