Short for '''TclExecuteByteCode''', is the guts of the Tcl [TclVM%|%virtual machine] and the [C] function that takes up most of generic/tclExecute.c, and (as the name suggests) is the main player when executing Tcl [bytecode].

Famous for being an example of how to not write your code — TEBC currently looks like a bomb exploded in it (“''don't look at it after lunch''”) — but hard to do in any other way; optimized bytecode executors usually are huge balls of spaghetti.

[DKF]: Note that you can't call this function directly, even from within the rest of Tcl. That's what `[Tcl_Eval]` (and friends) are for.
