Surely we're capable of walking and chewing gum as the same time? I
submit as long as "->" does not have text to on one side or the
other, it won't be confused with the very nice Scheme "from->to"
conversion convention.

I can't see how two names for the same thing wouldn't also "decrease
readability and accessibility of code a lot."  Do we do that anywhere
else in Scheme??

As someone who's used Clojure in anger (before returning to Scheme),
there's a great deal of value to using the Clojure syntax as much as
makes sense.  Pipelining is also a non-standard method of flow
control, so I prefer it uses a special syntax convention that always
includes non-alpha characters like "->".

BTW, I agree that using "threading" is a bad idea.  "Pipelining"
strikes me as the best, it's more unique (sorry) than "sequencing".
