I could be mistaken, but I thought Tcl would still reduce the function
text to bytecode behind-the-scenes.

We are losing with unnecessary text conversions in a number of places in
pltcl, but I think it's just in parameter passing at pltcl function
entry/exit and calls to the special Tcl commands provided by pltcl.
If you're executing regular Tcl commands inside a pltcl function,
I think you still will get benefit from Tcl 8's speedups.
