One of my favourite features of Tcl is that added
features are Tcl-like rather than faithfully
reflecting the constraints of C into the scripting
environment.  For example, much of the complexity
of using sockets disappears and creating/using
web services is a breeze.

For popen2 I think

        [in, out] = popen2('echo');
   fprintf(in,"hello");
   response = fgets(out);
   disp response

is more readable than

   p = popen2('echo');
   fprintf(p(1),"hello");
   response = fgets(p(2));
   disp response

so I would prefer the former interface.
