[swift-evolution] Alternative For Nested If Repetiion

[Ted F.A. van Gaalen]

a block of nested 'if else’  is not really nice, i think: 
	
	• if condition 1 {
	• statements to execute if condition 1 is true
	• } else if condition 2 {
	• statements to execute if condition 2 is true
	• } else {
	• statements to execute if both conditions are false
	• }

what I currently do to prevent this:

 switch true
 { 
case  film == 2010: 
         itsFullOfStars(monolith)
     
case terriblyWrongPresident():
        initiateNewElections()

case b > c:
        c = b

case d > c: 
        c = d

default:
       break    // or something else to do, if all other conditions are fase
}


This works perfectly well, looks good too, I think, but is it right thing to do it this way,
as in principle 'switch’  is perhaps more intended to evaluate variables?

Python has its “elif”  keyword… 

So what about, an ‘ifs’  statement group in Swift:  


ifcases      // or another keyword, perhaps                   
{
 case a > b: 
    b = a
case  c < d:
   b = c
} 
without  fall-through option. 
perhaps also without  default


What do you think?
