    proc inGlobalScope {} {
        uplevel #0 {
            # this is the proc body
            # with global vars
        }
    }

have some care about variables in different scopes though:

    proc inglobal {x} {
        puts $x
        uplevel #0 {puts $x}
    }
    set x fred
    inglobal joe
