I've had the same problem and yes, it would be nice for the scope to extend to
the while expression.

I would imagine that this is not normally supported because of the possibility
that an identifier may be redefined within an inner block, e.g.

int a;
do
{
int a;
blah...
}while (a == 1);

Which "a" is referenced within the while expression?

Fortunately, since D does not allow multiple definitions, this should not be an
issue.

Such a loop is a nonsense anyway, since it either loops only once, or 
never stops, depending on the value of outermost a. That's most probably 
not what the average coder wants when he writes that.
