What I want to do is parse an argument to a tcl proc as a string without any evaluation. For example if I had a trivial proc that just prints out it's arguments:

proc test { args } { puts "the args are $args" }

What I'd like to do is call it with:

test [list [expr 1+1] [expr 2+2]]

And NOT have tcl evaluate the [list [expr 1+1] [expr 2+2]]. Or even if it evaluated it I'd still like to have the original command line. Thus with the trivial "test" proc above I'd like to be able to return:

the args are [list [expr 1+1] [expr 2+2]]

Is this possible in tcl 8.4 ?

Thank you.
