Re: Good To Hear !
I'm not doubting it's well designed but it still was a commercial failure, some of the reasons why it did not do well in the marketplace are here.
On the subject of memory management, only Algol 68 had a heap and even then it only had a command to allocate memory, not to free it. Garbage collection if it existed was left as an exercise for the implemention.
If I write C or Pascal programs like that I avoid all use-after-free vulnerabilities as well. Therefore our friend who uses every C/C++ or Rust story to wax lyrical about Algol is spouting nonsense.
