struct CompressionData
{
     ubyte[4096] x; // note this is already [0...0] thanks
                    // to default init... but still:

     this ()
     {
         x[] = 0;
     }
}


--- Or even: ---

import std.range;

struct CompressionData
{
     ubyte[4096] x = repeat( 0 )[ 0 .. 4096 ];
}

Assuming repeat()[] is CTFE-able (didn't test).
