That was a booby trap of mine :-)
I have no other comments about your last response.
I have to agree with most of it. BTW, you did
s good job with your proposal.
I am attaching the little gadget I mentioned
before.
All the best

It's really nothing, a little gadget, but quite covenient,
because it abstracts away and composes
many functions into one.
Something similar to operator (.) in Haskel, as in:
f = g . h . k
It also allows for making quick and dirty
temporary functions:
pipe: func [
{Make a pipeline from a block of functions}
fs [block!]
/local result [function!]
][
make function! [x] append copy fs 'x
]
filter pipe [6 < ] .. [1 20]
map pipe [10 * sine] ..[1 10]
g: pipe [10 * sine]
source g
==g: func [x][10 * sine x]
Do you recognize this?
g: pipe [boom2 boom2 boom2 boom2]
g 1
== 61
Well that's ack 3 3 from the example I previously posted.
How about putting a probe after each stage of the pipeline?
