Is it somehow possible to check for a range with the match statement?

like:

match myVariable:
   0 - 9:
     Do this.
   10 - 99:
     Do that.

No, match checks for matches, not ranges.

True. But the idea of adding support for ranges and negations has been proposed before and is still in discussion: Add support for range comparisons and negation in `match` operations · Issue #994 · godotengine/godot-proposals · GitHub

I caught myself in a situation where this feature would be really really useful and save me some time and lines. I hope they implement it or something related to it. If they do and someone knows it, tell us about it, please!

match can’t do this, but if statement would be equally space-eficcient :

 if range(0,9).has(x):

Also, You can introduce an array with borders of your ranges:

var borders = [0,10,100,267]

and check what index would your variable get if it was sorted into this array. Then You would be able to match the result

With Pattern Guards, yes

var x = 123
	
	match true:
		_ when x > 100 && x < 200:
			print("1")
		
		_ when x < 100:
			print("2")
		
		_ when x > 200:
			print("3")
