I learned Math in a french-system school and yes, that's definitely a much better notation in my opinion. The difference between [] and () is not immediately clear, whereas [a,b] versus ]a,b[ makes it obvious that one includes a and b while the other does not. It also makes it easy to remember "open" and "closed" and what they mean in terms of whether or not the interval bounds are included or excluded

I don't know if it's very intuitive given that a and be are still inside the ][. Maybe a]..[b would make it clearer?

    a[..]b

just a][b :)

I learned it one way in Middle School and the other in High School. What's perplexing is that the schools were literally next door to each other, and in the same school system too.
