-SYNOPSIS
- list ?arg arg ...?
-_________________________________________________________________
-
-DESCRIPTION
- This command returns a list comprised of all the args, or an
empty
- string if no args are specified. Braces and backslashes get added
as
- necessary, so that the lindex command may be used on the result to
re-
- extract the original arguments, and also so that eval may be used
to
- execute the resulting list, with arg1 comprising the command's name
and
- the other args comprising its arguments. List produces slightly
dif-
- ferent results than concat: concat removes one level of
grouping
- before forming the list, while list works directly from the
original
- arguments. For example, the command
- list a b {c d e} {f {g h}}
- will return
- a b {c d e} {f {g h}}
- while concat with the same arguments will return
- a b c d e f {g h}

We need to also make sure that we /take/ any PMC and try to do the right
thing. Don't /require/ that someone pass in a TclString when a PerlString
will work fine, thanks. This is now a bigger issue when using the [list] ops.
