so I have a bunch of enums (0 .. n) that i also want to

use like:
enum blah
{
foo,
bar,
baz,
}
alias blahFlags = EnumToFlags!blah;
static assert(blahFlags.baz == 1 << blah.baz)
Take a look at the BitFlags template as well. It won't create
such an enum for you, but will provide a convenient wrapper for
using it afterword:
