I know that and for me, this is an unpleasant pitfall of D, especially
for array declaration:
int[Y][X] t; and then t[x][y] = ...
t: [X]->[Y]->int; and then t[x][y] = ...
Honnestly which reads better?
I know that D used to be (is still?) compatible with C declaration, but
if helps for the array declaration (int t[X][Y];) but, this is a mess
when there are pointers..

I do agree that this is a big change and don't expect to see it in D,
and in fact I'm so used to C's declaration that personnaly it's not a
problem, but I do remember clearly that I had a hard time learning them
while beginning C and I expect D beginners to have the same problem..
which is a pity.
Oh well, at least hopefully the out-of-bound exception will show them
the mistake quicky (far from sure of course as it depends on the value
used), but it is still a pitfall.
