4 major problems of pattern matching in Julia

I think there are many situations where the pattern matching depends on runtime values and therefore has a lot of overhead when it happens in an inner loop. In this cases the multiple dispatch pattern can have significant overhead. Interestingly, after spending some time for a larger project in Rust and using its Enums+Pattern matching extensively, I had for the first time feeling that there was a feature in another programming language that Julia did not have and which I wished it had. see ru…

I agree with the feeling that using enums + pattern matching in Rust and parametric multiple dispatch in Julia seem good for now.
