Except ** does not flatten recursively, so:
my $lines = [ =$fh ];
is still borked.
Do we want a *** "nuke everything flat" semantic device, if not the
operator? Or an eager context on the right hand side of "="?
On the other hand, we can alternatively specify that closing a
file handle must force all thunks associated to it, i.e. in this
case fill @lines with real data. Pugs can do that just fine, but I
have no idea how parrot is to achieve that...
