I believe you have done it, sir:

It is proof against glob or variable expansion, it swallows redirection, 
and it doesn't mind compound command lines, however it does expand 
bangchar, as wanted:

    $ test ls $PWD; test ls g* > /dev/null; test l ,H $PWD/test; test 'I
    wandered \n lonely as a cloud'; test "that \n floats on high"

    My unexpanded arguments were:  ls $PWD

    ...and my arguments broken to an array:

    two:   ls
    three: $PWD
    four:
    five:
    six:
    My unexpanded arguments were:  ls g* > /dev/null

    ...and my arguments broken to an array:

    two:   ls
    three: g*
    four:  >
    five:  /dev/null
    six:

    My unexpanded arguments were:  l ,H $PWD/test

    ...and my arguments broken to an array:

    two:   l
    three: ,H
    four:  $PWD/test
    five:
    six:

    My unexpanded arguments were:  'I wandered \n lonely as a cloud'

    ...and my arguments broken to an array:

    two:   'I
    three: wandered
    four:  \n
    five:  lonely
    six:   as

    My unexpanded arguments were:  "that \n floats on high"

    ...and my arguments broken to an array:

    two:   "that
    three: \n
    four:  floats
    five:  on
    six:   high"


... I think I can't even  quibble about the quoted strings not being 
treated as single arguments
because I can't have it both ways--the whole exercise is to have zero 
processing.

And I don't even need to rape the src.
