ML has a TCL look to it,

Actually, TCL has a LISP look to it (this was explicitly mentioned in the orginal paper on TCL (external link)). Though it's far too limited to provide a lot of the cool-factor that LISP provides.

ML comes out of Functional Programming, just like LISP, so it's not that surprising that it looks a little like TCL to some people. But the similarties are only on the surface.
