Looks kind of like MAP to me.
map: func [fn blk args /local result][
result: copy []
repeat el blk [append/only result fn :el args]
result
]
>> map :odd? [1 3 5 7 9 12] none
== [true true true true true false]
You might also look for old discussions here on the COLLECT functions
some people have done.
