[REBOL] Re: dirty editor

Hi Gerard,
I have only a little time, so I'll be brief and I'm sure others will chime
in as well.
<<

I know this one has to do with "contexts" but how does it differ from mine?
Is there more to know about this way of doing things that could be of
interest to me and others too that I didn't find yet ?
What is the impact of requiring the content of ctx-text by the way of the
get in
instead of probing it directly as I did?
I don't see any real difference here but may be in other situations it could
be different ...

As you have found, there are many ways to locate information reflectively in
REBOL. I was trying to show just the function responsible for the editing
operation, so I used "get in" to look inside its parent context (in order to
make PROBE happy).

true

Can it really be so or did I goofed my VIEW somewhere ? For which situation
can ctx-edit not be a BLOCK if this is possible? >>
There are similarly named items that are not quite the same, and may be
confusing. I haven't spent time analyzing their relationships in detail, but
you can do this to see that ctx-text and ctx-edit are different datatypes.
>> type? ctx-text
== object!
>> type? get in ctx-text 'edit-text
== function!
>> type? ctx-edit
== block!
ctx-text also contains a reference to view*, which contains many circular
references so, while you can PROBE ctx-edit, doing a PROBE on ctx-text will
give you a very long listing indeed.
