Phobos's style guidelines prohibit all caps. Manifest constants are camelCased 
just like variables and functions are. So, the standard library doesn't have 
anything which is all caps unless it's old code and doesn't follow Phobos' 
current style guidelines.

Personally, I think that all caps is hideous. It makes sense in C/C++ for 
macros due to how the preprocessor works, but it's completely unnecessary in 
D. I'm sure that some people still use all caps though.
