There are downsides, Jonathan Davis has written about them: 
http://www.jmdavisprog.com/articles/why-const-sucks.html


But the downside of D's `const` or `immutable` are mainly that 
you can't use them everywhere you might wish to. A good rule of 
thumb is that if you can get it to pass compilation as `const` or 
`immutable` without any hacks, there is no problem going ahead 
with it.


To use or not immutable?

2020-12-09 Thread Jack via Digitalmars-d-learn
I'm coding with visual studio code and now it shows a yellow mark 
on variables that is never modified and that could be marked as 
const or immutable. I think that makes sense, so I think I'll be 
using it. Do you use it in your code base? are there some design 
flaws, like there's in C++'s const, which I'm not aware of?
