You want to make use of "eval":
proc foo {args} {
eval bar $args
}
proc bar {args} {
puts stdout [info level 0]
}
eval "breaks out" one level of list structure. You have to watch
out that you preserve args that need to remain such. Like so:
proc foo {cmd args} {
eval [list bar $cmd] $args
}
proc bar {cmd args} {
puts [info level 0]
}
