Log:
- Change [expr] to call the "interpret" method on each operand
- Add "interpret" methods to TclInt and TclFloat
- Change TclConst to inherit from String instead of TclString (to fix `if $P0
goto ...`)
- Disable tests which use [expr] with variables and comparison operators with
an operand > 9 (variables aren't being turned into numbers yet)
