Over 2 years ago I created code to test compile time computation of Fortran: [Computing at compile time](https://fortran-lang.discourse.group/t/computing-at-compile-time/3044). We are super excited to announce that LFortran can now compile the example too, and is very fast at the speed of compilation:

- [LFortran: the Fastest Open-Source Compiler in Compile-Time Evaluation of an Array Benchmark -](https://lfortran.org/blog/2024/06/lfortran-the-fastest-open-source-compiler-in-compile-time-evaluation-of-an-array-benchmark/)

Big thanks to @HarshitaKalani and @Pranavchiku for implementing the missing compile time features.

I remember getting into trouble with several compiler vendors when I tried to report ‘bugs’ in their compilers when trying to initialise a 143,000+ word dictionary by initialisation at compile time, i.e. with 143,000+ source statements doing the initalisation.

Very happy to be helpful as you embark on it. Glad to see LFortran progressing at this wonderful pace. Looking forward to reach beta soon
