This proposal consists in adding a functionally that I find useful in VB .net,
that lets you set a default return value of a function at the begging rather
than at the end
current:
func myComplexOperation() -> Int {
//Some long complex code that might return some value
//Default return at the very end
return 0
}
proposal:
func myComplexOperation() -> Int {
//set the default return at the begging using the ‘default’ keyword or
some other keyword
default 0
//Some long complex code that might return a value
//if the end of the function is reached, return the default
}
The other alternative will be to allow naming the return value
proposal2:
func myComplexOperation() -> result:Int {
//set the default return at the begging using the output variable name
result = 0
//Some long complex code that might return some value
}
Another alternative will be to set the default value directly like and optional
parameter
proposal3:
func myComplexOperation() -> Int = 0 {
//Some long complex code that might return some value
}
In all of the cases the compiler will check that a default return is set before
exiting the function
It could be some combination of the 3 proposals
Thanks
