Stream is used differently in Tcl and Unix.
Minded separation Python from functional approach (deprecation of filter,
doubtfulness of implementing tail recursion optimization) probably it is not
inspiring for regular python programmer.
Lazy "streams" are a good thing provided they can be easily used for
organizing data pathes and connections.

Construct, Glue, Merge?
Taken readability any whole word is better.

copy is already using construct in python. Why not use it?

If I got the intend of Stream correctly, I wish use them as Tcl streams,
so I'd need combining and filtering and i/o.
