Ouch! That's a large amount of code.
Isn't this easier?
>> length? Arguments :copy
== 1

Arguments: func [
{Returns the arguments of the function as a block of word! values.}
F [any-function!] "The Function"
][
head clear any [
find first :F refinement!
tail first :F
]
]
And if one needs the length of a path:
>> length? 'copy/part
== 2
Or perhaps I've misunderstood something?
