Actually, an external tool could detect when a bool is passed as 
an argument to a function and warn when not done with a named 
argument. This would free library APIs from having to use Flag 
when some users don't care about it. The cost would come in a bit 
more build system complexity/build time, which might mean a lot 
less enforcement due to inertia. Though maybe a reasonable 
trade-off.
