I wish I could use D for everything

I tend to use printf for debugging because writefln requires a lot of 
the compiler/library to be working correctly for it to work. printf 
requires practically nothing in D to work correctly, so it is ideal for 
debugging the compiler and the library.

I use writefln pretty much exclusively when developing an app in D, for 
the straightforward reason that writefln is much simpler, safer, and 
more powerful than printf.

Some of my older D app code uses printf because writefln didn't exist 
way back.
