Excellent.

However will the compiler align all static arrays so their memory
begins at a proper offset?

Maybe a more appropriate question is: Is all stack data guaranteed to
be properly aligned, and on all platforms? For example:

    enum Size = paddedSize!C;

    ubyte[1] preBuffer;

    ubyte[Size][2] buffer;

Is 'buffer' guaranteed to be aligned so its memory begins at a good
offset? There could be any number of bytes before 'buffer', such as
the preBuffer above it.

Tests show that they are indeed aligned, but I wonder if this is
something you can guarantee on all platforms?
