@torfjelde should we improve this PR by incorporating TuringBenchmarks ? Alternatively, we can move all benchmarking code here into TuringBenchmarks . I am happy with both cases, but ideally, these benchmarking utilities should live in only one place to minimise confusion.

Also, https://github.com/TuringLang/TuringExamples contains some very old benchmarking code.
