If my way of thinking of variables as having an input port and an output
port, i.e. as a way of giving a pipe of flowing data a name for later
reuse, then it becomes a lightweight way of specifying the identity
step.
That is, I claim that
... -> ...
is equivalent to
... -> identity() -> ...
is equivalent to
... >> $foo
[$foo] -> ...
with an added name for later reuse.
Which brings me back to thinking that the -> vs. >> distinction is
misleading at best, and I should just be able to write
... -> $foo -> ...
