I am not proposing it.  It is a solution more in the CMake style, but I 
am not proposing it.  There is no value add over simply using IF(COND) 
.. ELSE(COND) statements.  The user can indent the code any way he wants 
to avoid the "line crawl."

The problem with your proposal is you want to reduce clutter at the 
expense of safety.  I don't personally think it's a good idea.  If 
safety concerns are addressed, you end up with exactly what is already 
available: IF(COND) .. ELSE(COND) and you're responsible for your 
indenting as you see fit.
