I am very glad to note that the [LFortran webpage](https://lfortran.org/blog/2019/05/why-to-use-fortran-for-new-projects/) lists the native support for matrices and matrix/vector operations as the **top two highlights of Fortran** :

> - Operators which operate naturally upon the aforementioned arrays/matrices, as they do scalars;

This is reassuring, because I thought I was among the minority when regarding such support as a core strength of Fortran, and I even thought I totally misunderstood modern Fortran.

Now, it seems that my understanding of Fortran is at least akin to the viewpoint of LFortran developers. Great! This viewpoint is also an indication that LFortran will pay more attention to [the robustness and performance of intrinsic array procedures](https://fortran-lang.discourse.group/t/testing-the-performance-of-matmul-under-default-compiler-settings/4096) such as `matmul`. This gives me yet another reason to look forward to using LFortran for my projects, in addition to many others including interactivity.
