I find it shocking that anyone would consider 15 seconds slow to compile for a 
large program. Yes, D's builds are lightning fast in general, and 15 seconds 
is probably a longer build, but calling 15 seconds "slow-to-compile" just 
about blows my mind. 15 seconds for a large program is _fast_. If anyone 
complains about a large program taking 15 seconds to build, then they're just 
plain spoiled or naive. I've dealt with _Java_ apps which took in the realm of 
10 minutes to compile, let alone C++ apps which take _hours_ to compile. 15 
seconds is a godsend.
