I think this is a big improvement over C's "spiral" way of
reading types:

I guess it could've been left to right, but... it's okay.
The way I see it, English "of" flips its operands backwards
compared to English's [adjective][noun] syntax:
int an_integer;
int* an_integer_pointer;
int[] an_integer_array;
int[3]* an_integer_array(length 3)_pointer;
But granted, in English, "of" is more scalable than
[adjective][noun].
