Re: Do I need to refactor this code?

sequence temp 
temp = {a,b,c,d,e,f,g,h,i,x} 
 
switch temp do 
    case {0,1,2,3,4,5,6,7,8,9} then return 1 end case 
    case {0,1,2,3,4,5,6,7,8,10} then return 2 end case 
    case {0,1,2,3,4,5,6,7,8,11} then return 3 end case 
end switch 

Pretty in many ways. Is there a "don't care" value, or a helpful hint to catch a error or fall-thru in the Eu source code, such that

sequence temp 
temp = {0,1,2,3,4,5,6,7,"<12",9} 
 
switch temp do 
    -- "" = type sequence flag = "don't care" (yeas, aka an error) 
    case {0,1,2,3,4,5,6,7,"",9} then return {1,temp} end case 
end switch 

So while Eu didn't process the "<12", temp is otherwise tested and returned to the user in a sequence for extra processing?

Or praps this:

type P_1(integer x) 
    return x >= 0 and x <= 23 
end type 
sequence temp 
temp = {atom,atom,atom,atom,atom,atom,atom,atom,P_1,atom} 
 
switch temp do 
    case {0,1,2,3,4,5,6,7,12,9} then return 1 end case 
end switch 

Or praps there is some way to push a list of types into the case comparisons internally on a case-by-case basis?

I have also had a situation where this would have been extremely valuable in optical pattern recognition or extracting details about motion. It would also be handy in resolving tags in content addressable data, or misspelling, or ?
