First, there isn't a streamed sam, and second, streaming only works
for one file.  Second, you *can* stream text through commands; I do it
all the time.  (|fmt, |sort, |tr A-Z a-z, etc.  etc.)

But to answer your question: I find the X command extremely powerful,
and can't see any way to have a streaming implementation that will
look at multiple files simultaneously.

One day I realized I could easily implement Edit as a command in acme,
but that after about fifteen years of desultory thought I still didn't
see the right way to build a stream sam.  The X command was the
clincher, and I started hacking.
