Pattern matching with guards does not allow multiple matches.

[viesturz]

Hi,

I want to match multiple patterns with guards to a single code block.
I was wondering if there is any reason why the following code does not compile?

let b = (3i,4i);
let g = 0i;
match b {
   (2,_) | (_, 2) => println!("2 inside "), // this works fine
   (2,_) if g > 0 => println!("First is 2 and some guards"), // also works fine
   (2,_) if g > 0 | (_, 2) => println!("2 inside and some guards"), // this does not compile
   ....
}

Also have you considered allowing to use a general if condition syntax in matches, like this?

   ((2,_) && g > 0) || (_, 2) => 

Edit:

Also this does compile, but looks a bit ambiguous to what part of the pattern the guard applies to.

(2,_) | (_, 2) if g > 0 => println!("2 inside and some filters"),

See RFC #99, a postponed RFC that would add this feature among others.

I just ran into the same issue. Is there any update on this?
