Why it is bad? Before, the criticism of pointers was based on the fact that pointers are d= angerous. So, Ada is better, because it avoids these dangers. Now we have guys with *safe* pointers and what? They are bad, because they = use pointers? And pointers are bad, because they are dange... wait, somethi= ng's went wrong.

And you still wonder why you are not convincing and cannot attract newcomer= s to the language. So, seriously - what's wrong with pointers in Rust? My personal argument would be that their syntax and learning curve behind t= he involved idioms are making the code very difficult to comprehend. But th= is is the rational argument that was not mentioned here, you have instead s= tayed at the level of "curly braces are bad". Are there other rational argu= ments? --=20 Maciej Sobczak * http://www.inspirel.com
