lang/nim - The NetBSD Packages Collection

Nim (formerly known as "Nimrod") is a statically typed, imperative
programming language that tries to give the programmer ultimate power
without compromises on runtime efficiency. This means it focuses on
compile-time mechanisms in all their various forms.

Beneath a nice infix/indentation based syntax with a powerful (AST based,
hygienic) macro system lies a semantic model that supports a soft realtime
GC on thread local heaps. Asynchronous message passing is used between
threads, so no "stop the world" mechanism is necessary. An unsafe shared
memory heap is also provided for the increased efficiency that results from
that model.
