Hi, all
this works also with foreach (not only with loop and repeat):
use [insert-only break-return res] [
insert-only: func [series value] [insert/only series value]
break-return: func [value] [break/return value]
res: func [value] [func [] reduce [value]]
collectB: func [
{Collects block evaluations, use as body in For, Repeat, etc.}
block [block!] "Block to evaluate."
/initial result [series!] "Initialize the result."
/only "Inserts into result using the Only refinement."
][
initial: res reduce [none any [make result result make block! 10]]
reduce [
:loop 1 reduce [
:change :initial reduce [:break-return]
pick reduce [:insert :insert-only] not only
:tail :second :initial :do block
;:do block could be to-paren block, to make it a little more fast
; but so the block is copyed
:change :initial none
]
:do :initial
]
]
]
