Subject: case statement and ranges

Hey, I want to do something like that:

case amount
when 25..50: 42
when 51..66: 78
when 90..123: 99
end

which works of course.

Now what I would like to have some other cases like when amount is lower
that 25, but with no minimum, or when it is higher that 123 ...
I could write something like:

case
when amount === (25..50): 42
when amount === (51..66): 78
when amount === (90..123): 99
when amount < 25: 100
when amount > 123: 200
else 0 # this would happen only when amount is in 67...90
end

But it doesn't feel that well ... since I am repeating my amount
variable all the time and this is precisely what the 'case something'
construct is about.

I cold also use some extremely high and extremely low values in ranges,
like (123..100000000) or (-10000000..25) to handle the other cases since
I know that in my use, it would be fine. But it does look quite
inelegant ....

thx
