[REBOL] context of a function - Enhancement request Re:(3)

Hi Frank,

Aha, you wish to determine the equivalence of the BINDed word to the word
the same word IN the object's body. You then must know the index of the
local word you are comparing to in the object body i.e. your expression
first second second o

The equivalent also works with my in-func:

>> f: cfunc [a] [a]
>> same? second second :f in-func :f 'a
== true

I trust that the in-func function I proposed in my previous email, together
with cfunc and get-context-block help solve your serialization problem? Or
is there something I have overlooked?

Take Care,
