A number of difficult questions have arisen, and
continue to arise concerning the details about
how Tcl commands are evaluated.

This page has been created to lay out the
details of Tcl command evaluation in order
to see the various points at which existing
behavior might be modified, or new behavior
might be attached.

I find it easiest to follow the details by
working from the inside out.
