proc lproc {name args list} {

            ::apply [list {} {
                upvar 1 list list 
                ::foreach line $list[unset list] {
                    if {[catch {::uplevel 1 $line} cres copts]} {
                        dict incr copts -level
                        return -options $copts $cres
            } [namespace current]]
        } [uplevel 1 {namespace current}]
    ] $list]
