Just shooting from the hip:

"args" is a reserved name for arguments to procs which is
used to implement variable number arguments. "args" is
not a single argument, but an array.

I don't know what happens when "args" is last in the list of
arguments to a proc or if it even has a defined meaning...

It looks like you pass in an array instead of splitting it up
into individual arguments.

proc foo {args} {
    # how to forward this to proc "bar"?
    #
    # This is wrong, it passes in a single argument, an array to bar
    bar $args
    # This will work, except I'm not sure what happens in all the
    # escape rule cases... or is this 100% clean?
    eval "bar $args"

}
