I am sorry I missed your contribution on the subject somehow. I like it.
My two cents changing the behaviour of the function in cases like:
foreach head heads [...]
foreach insert inserts [...]
foreach tail tails [...]
foreach do does [...]
use [insert-only] [
insert-only: func [series value] [insert/only series value]
collect: func [
{Collects block evaluations, use as body in For, Repeat, etc.}
block [block!] "Block to evaluate."
/initial result [series!] "Initialise the result."
/only "Inserts into result using the Only refinement."
] [
result: any [make result result make block! 10]
reduce [
:head pick reduce [
:insert :insert-only
] not only :tail result :do block
]
]
]
