Not really, because the called function doesn't require parameters if
you always want a specific variable to be set, like Julia asked for:

$ tclsh
% proc g {} { uplevel set x 5; return }
% set x
can't read "x": no such variable
% g
% set x
5

This can't be done in C portably, and is certainly not call by
reference. And please, do not send me copies of your public ansers.
