If you made it fully dynamic, yes, and there are probably a lot of edge
cases to consider.  In your construct

when would you evaluate someproperty?  Before bar is scheduled?  If you
evaluate it when foo is about to execute it will be too late since bar
has already been run.

If we restricted deep-if to properties/conditions that can be evaluated
at parser time, then the dependency tree wouldn't change at runtime and
such a change wouldn't have as big an impact as a truely dynamic
