No, not a fundamental problem. I think I even hid that in some comment
in there, at least if it's decipharable by someone else than myself...
Basically I think it would be nice in the future to tidy this a little
bit and separate the actual container from the pipe itself - and have
the pipe just fill/use the same container.
