enum uint myAlignment = 16;
align(myAlignment) struct Foo {}
void main() {}


DMD 2.063alpha gives:

temp.d(2): Error: positive integer expected, not myAlignment


With this a single compile-time constant change is enough to modify at the same
time and in the same way for different CPUs various alignments in the code.
It's good to be more DRY and avoid magic constants.
