-1. This would require definition of what is a range and which types it support. Defining ranges of user-defined classes doesn't make sense and it would also be hard to implement.
There are two obvious definitions of a range: a range object, and a pair of inequalities. I'm not sure whether a range object is supported, but it's possible to use a built-in type with a guard as a range check: match thing: case int(n) if 1 <= n < 5: ... Or you can omit the type check and just use the guard: match thing: case n if 1 <= n < 5: ... Whether this is too cumbersome to be useful is up to the OP. (I'm not familiar with Rust so I don't know what "1..=5" means and whether or not each endpoint is included, so if I got the openness of the range wrong, just change whether it's "<=" or "<" as needed.)
