D - suppression of default initilisation

Hello world,

I started to use D on a pet project, and excited that it seems to match C++ in
speed.

I have a heavily called recursive function, each puts a fix sized array on the
stack. The call to memset to init the array slows things down.

Is there any way to suppress the automatic initialisation, or might there be
in the future, as the optimisation switches don't seem to change it.

Initialize it to void, e.g.: int[1024] foo = void;
