That's definitely what Walter would say. But I think it shouldn't
be the only argument to not add a feature to the language itself:
if some pattern is useful/frequent, and users implement it
themselves every time, it should be either implemented in the
compiler or in the standard library.
Besides that, it just seems inconsistent that D lacks this
particular feature: fixed-sized arrays are there, type deduction
is there, so where's type deduction for fixed-sized arrays?
Though I would argue that it's better to use '_' instead of '$'
to denote deduced fixed size, it seems more obvious to me:
int[_] array = [ 1, 2, 3 ];
