Can you do an example? Here it works (1.2.10.3.1).

before REBOL [] there is some no space chars
AND
there is not a newline between the chars and REBOL []
The only difference i see is this:
script? "aa^/rebol[]" ;== "aa^/rebol[]"
script? "aa^/[rebol[]" ;== "[rebol[]"
This could be a bug.
Note also that in the embedded case the final ] can be omitted.
So i think that this is enough:
load-header: func [
"Load and construct a Rebol header object"
str [file! url! string!]
][
if str: script? str [
attempt [
construct/with first load/next find find str "rebol" "["
system/standard/script
]
]
]
probe load-header "# aa^/rebol[needs: [1]]"
The function return none if the header block is bad formed, like in case like
these:
"rebol ["
Note that script? returns a positive answer in these cases:
script? "rebol ["
so we need the attempt in the function.
