It might be interesting to examine how the properties immutable/mutable
relate to the categories scalar/series.
I wonder if path! is really immutable, or whether something else is
going on, like its range of valid values is restrained.
Likewise for lit-path! and set-path!
Sometimes exceptions h
Mutable/immutable Rebol values.
Adding a correction and examples how you can change the state of
mutables.
The relations:
mutable <=> series
immutable <=> scalar
are pure coincidence, because you can have immutable series and
mutable scalars. It is simply a matter of preferences of the

I am not sure about that. If Disarm doesn't change the error
state, then error is immutable.

Can you provide a definition of mutable and immutable, Ladislav, and
explain why it's important.
If a word is protected, is it then suddenly immutable, or is it a
deeper question than that?

I think I'm to blame for introducing the word "immutable" into this
thread, so I'll throw in my understanding. The specifications for
The most simplified definition I can offer is, that mutable Rebol
values can change their state, while immutable can't. Maybe Joel

The importance?
1) if you have an executable code as an immutable value, it cannot
be self-modifying

But disarm takes an error and returns an object --- so you didn't

Hi,
would it be usefull to have 'first available to parse? I just can't find
example right now, but let's say I want to find something, but apply my

possibilities:

Hello,
I am working on setting up a secure and fast enironment for offering REBOL

Hi Ole, Petr,
Thank you very much for your comments.
Ole, you suggested this to find a word ending in "ing":
>> a: [skip a | "ing"]
== [skip a | "ing"]
>> parse "ringin" a
== false
>> parse "ringing" a
== true
That's fine, except it won't detect a word ending in "ing" in the
middle of the str

Yes. This would be useful, and I have been thinking about adding it for many months.
Do you think it is better as:
thru ["a" | "b" | "c"]
The first match is the winner.
