No, on the contrary, Austral is entirely built around resource management. The central concept is linear types, which is about ensuring 1) resources are disposed of and 2) resourced are used according to their protocol, e.g. no use-after-free.

There's "no garbage collection" because Austral lets you have manual memory management without the danger, like Rust.

There are no destructors in the sense of special destructor functions which are called implicity at the end of scope, or when the stack unwinds. Rather, you have to call the destructors yourself, explicitly, and if you forget the compiler will complain.

This sounds verbose until you start paying attention to all the mistakes you make all the time that involve, in some way, forgetting to use a value. The language makes it impossible to forget to do something.
