Steams : helpers ideas

[arnaudhe]

I think those streams helpers would be usefull:

stream::replace_"regex with the (token) I want to be replaced"_ "new"
to replace "token" in the matched regex by "new"

stream::from-file
even if it is only a cat command, it might be more readable

No problem for the stream::replace.

About from file, I'm not sure that its a good idea. We are just renaming a bash function. And which is the limit ? Why not create stream::fromurl (curl)... ?
