Did you also put the ` ~ type ~ ` on the 2 other cases where you 
use the variable type?

      mixin(`if (value.length == ` ~ type ~ `.sizeof)
                {
                   ubyte[` ~ type ~ `.sizeof] raw = value[0..$];
                   auto fValue = raw.littleEndianToNative!(` ~ 
type ~ `);
                   displayinfo(fValue);
                 }
                  break;
             `);
