Thank you for the explanation.

 So it's not going to be safe as in "type safe" but it may well be perfectly

As I described which is not quite how it works wouldn't be type safe as you
could put something without a method in then call that method but it would
be safe as like everything else in coding in it wouldn't break unless you
did something wrong.

polly<allMethodsAble> p1;

This would be useful, but if it won't do this then it's any_stream.

Contact the maintainer to find out if he wants to put the already
implemented stream support or <...able> into any.
