However, those expectations are based on the inside-out syntax of C.
Naturally, wanting to be consistent, especially compared to C, D should
deviate from that syntax.

That is sane: It is alwasy "first the type then the size":
Following from that rule (i.e. first type, then size), how would I have
an array of 3 elements where each element is an array of 4 elements.
Let's see... Each element is int. There:
Then, I want an array of 3 of those. There:
This is one of the commonish arguments in the D forums that I have the
strongest opinion because there is no problem with D's syntax at all. It
It is consistent even when indexing. The index is for the array:
a; // the first element of a; it is an int
b; // the first element of b; it is an int
I don't see any problem at all. :)
Remembering that there is no such thing as a multi-dimensional array in
D (nor C), it just follows naturally:
b; // the second int of the first int

That's beyond ridiculous. I am glad that D avoided that problem for both
function pointers and arrays.

That makes perfect sense to me, because this is a function API, not D
syntax. There is no ambiguity in saying "you go deeper into the element
sizes as you provide the arguments."
