All true, except one crucial fact: DMD gets critical bug fixes 
incorporated with new features in the same release. This leaves a 
poor choice to the programmer, either he sticks with older 
compiler version and can't get any critical bug fixes, or he 
updates the compiler to latest version with all the bug fixes but 
risks breakage of code due to new features (which is _exactly_ 
what happened to manu).

It's high time for D to split its dev version from the stable 
one. All major software have this, Debian, Linux, browsers 
(chrome, Firefox, etc), Windows, etc, etc. This is an ancient 
concept practiced for decades now in the software world.
