That's a classic misconception that people have with Tcl. It is
so much faster than most people "remember" it being, as they all
worked with the pre-on-the-fly-compiler version. Tcl 8.0 changed
the rules and 8.4 pushed them again.

You can see version speed differences at
In the simple case of list iteration (#255), 8.4 is more than 240x
faster than 7.6!

Doubt all you want, the truth is Tcl has improved a lot. :)
