Of course you are declaring AA here because D does not support variable arrays
like C. Sizeof property in this context is treated as type, not expression -
that's why sizeof yileds ulong, not 4.
If you wanted to have static array here, then this is invalid report. However,
if you want this to compile as AA array, than this is really rejects-valid. On
the other hand, this is useless - in such cases Foo[bar.sizeof] always yileds
Foo[ulong].
