Let me restate the question. Suppose I have a script:

set script {
array set foo $pairs
set bar $somethingElse
}

This would typically have been passed into a procedure instead of set
literally, where "pairs" and "somethingElse" would be defined in the
caller's context. I want to be able to run the same script either
locally or remotely. No preprocessing is necessary to run it locally.
I know I have to substitute variables locally before I can set them
remotely, and a simple [subst] won't do it. I don't think
[list]-ifying it in the caller's context, as you suggest, will work
either, because it'd lose the whitespace command delimiters. I could
process each line, substituting each word on the line and preserving it
as a single word, then reassembling the substituted script, but is that
the only way?

I may have oversimplified things in my original posting by using a
single-line script... sorry!
