I don't want to get the context, Or the value of the word. I want to get
a word bound to the context of the function. That is a difference.
make-fun: func [/local a] [
f: func [a] [a]
append second :f 'a
]
>> make-fun
>> probe :f
func [a] [a a]
To serialize function "f" I must have a chance to find out, which of
the words are bound to function "f"s context and which not.
This binding must be persistent. I think it would be a good idea, if
make function! would bind the third and first of the function to functions
context.
