Re: And another crm114 script language question about 'isolate'

Ja-a-a-aaa, so far with you all the way. But-t-t-t lemme rephrase: the
wonder starts (started, I should say) here:

{
    window
    isolate (:a:)           # --> 'a'
    output /a = ':*:a:'\n/  #
    isolate (:a:) /foo/     # --> 'foo' (override; old 'a' is lost
    output /a = ':*:a:'\n/  #
    isolate <default> (:a:) /bar/  # --> in this case, :a: will _stay_ 'foo'
    output /a = ':*:a:'\n/  #
    isolate (:a:)
    output /a = ':*:a:'\n/  # now what do you expect here? Then run
and see if reality matches brain. For me it didn't.
}

(source attached)

Please think about the last isolate before you check and run it: this
is a perception check after all.



I have learned the hard way that I had forgotten something important
about 'isolate' and why it is called exactly that ('isolate', and not,
say, 'instantiate', 'declare' or 'allocate')

PS: answer to my own question is: yes, it's proper and intended to be like that.
Only when you're passing through the boundary from command
line-declaration of a variable (--variable) into the script code
proper, it threw me when I wrote 'isolate (:var:)' assuming it would
be a quick hack to disable a commandline-specified variable. I was
wrong, because without the // isolate assumes a default behaviour I'm
not used to in other languages. Neverthless, one fitfull night and it
makes sense again.
