Yep, agree. I was asking about a non-external solution, but I had overlooked Joao solution.

thanks for the advice.

1. Re: number stream in ascending order (Frank Barknecht)

That's the same as the idiom Jo?o showed before, except that it requires users
to install an external object. I'd recommend to use Jo?o's version, maybe
extended like this:

[t f f f]
| \/
| /\
| [- ]
| |
| [> 0]
| \
[spigot]
|

Ci?o,
