While I can understand your request and do support it (sorta ;)), I  
think
it should be well considered to add expressions, even if they are "just"
boolean. It might awake those sleeping wishes for full fledged  
arithmetics
and such beasts (aka The Bad Thing(tm)).

As a workaround you can always provide template variables which have the
value of those boolean expressions if that would make your life that  
much easier.
After all the controller is allowed to know about the logic of the  
view. It still
wouldn't compromise the MVC pattern of ST, as long as there isn't any  
actual text in
the controller.

This is the way I handle things at work (where we have a template  
system quite similar to
ST) and that works pretty well. Having boolean expressions naturally  
simplifies things when
the requirements change, but it would require some work in the  
grammar (which may or may not
be easy/quick to do, I don't know for sure).
