Return in SRON

If you want to return a value from a function, then 'return' attribute is used.

Below is a sample code:

{
    name : square
    args : (Int val)
    return : ~{ val^2 }~
}

{
    name : Main
    Int val = square(7)
    println(val)
}

• You can return value of any type from a function.

• You cannot return multiple values from a function.

• Using 'type' attribute, you can also specify the type of the value to be return from a function.

{
    name : get_list
    type : List
    return : ["Hello","SRON!"]
}

You can also set the return type of the function and for that you can use 'type' attribute. 'Type' attribute converts the return value to the specified datatype only if the datatype of returned value is not same.

{
    name : get_value
    type : Int
    return : 3.1415   @this value will be automatically converted to integer
}

SRON uses advance return value optimization to enhance code speed and efficiency. Even if the size of the value is too big, it doesn't affect the code performance.
