Doesn't seem to. I replaced the quotes with braces (patch attached)
and got:

Maybe there's something more to do? I've read again the chapter
about eval in my tcl manual and it says the difference between using
a list and curly braces is that the latter doesn't make variable
substitution immediate, which could be dangerous if the eval is
going to be used in another scope.

But I don't understand what this has to do with the "Too many
positional parameters" thing. Evil tcl substitution rules...
