It's too bad C's pointer-deref operator is prefix instead of postfix. In Pascal it's ^ so you write ptr^.member and there's no special -> operator. Even better, declarations and expressions would read intuitively left-to-right instead of spiraling out through stars on the left and brackets on the right.
- btrask 6y agoIn C you can use [0] for postfix pointer dereferencing.
- abecedarius 6y agoAlas, that's clumsy, and for declarations not possible. I have used it in expressions at times. Here's a variation that seems plausible: make postfix p^ be like C's p[0], and infix p^i like C's p[i]. (With a tighter binding for ^ than C has.)
