I think we are running into a limitation of what can be done, feasibly. I see
your point, however, I think it's nearly impossible w/out some huge rewrites.
Currently nothing can be executed until the whole app is translated into IL code.
So, functions that return values or dynamic if statements are currently out of
the question for the potential of omitting code. A new keyword was needed that
would do very limited decision making based on values that are known at parse
time, hence the defined words that are handled at parse time via command line and
using the with keyword (which is a parse time keyword as well).
