[fpc-devel] Aligned dynamic arrays

 I always get nervous of mode switches because it's hard to remember them
or realise they exist, and it feels a little hacky, like it's a kind of
compatibility setting more than anything else.  Like at one point, I
preferred there was an explicit way to set a type's alignment so there's no
ambiguity or risk of bugs if a different setting is used or otherwise
overridden.  e.g.

 type  TVector4f = packed record
     x, y, z, w: Single;
   end align 16;

 Just my thought.

 And some people still ask for more modeswitches...
