in reply to This is not a pipe

How abstract do you want it? 

ref($this) ne 'Pipe';
ref($_) ne 'Pipe';     # $_ is a topicaliser, so is "this" - thus, "th
+is" == "$_"
! UNIVERSAL::can($this, 'smoke');
$_->can('smoke');

Perl 6 ok? 
!.isa('Pipe');

Just wondering.

Update: Missed the ! on the perl6 code.
