 You forgot
 
 char.init 0xFF
 wchar.init 0xFFFF
 dchar.init 0xFFFFFFFF


One small disadvantage of some of those init values (for not int variables) is
that if you have a large global static array of floats or chars in your
program, its memory can be found in the binary, that can become huge (you can
avoid that setting the static array to void, and then I think the LDC compiler
or the operating system resets such memory to zero anyway).

To avoid such huge binaries D can keep small static arrays like now, but it can
initialize at run-time (before the main) the large static arrays.
