Often when deconstructing a tuple or calling a method with out parameters, you're forced to define a variable whose value you don't care about and don't intend to use. C# adds support for discards to handle this scenario. A discard is a write-only variable whose name is _ (the underscore character); you can assign all of the values that you intend to discard to the single variable. A discard is like an unassigned variable; apart from the assignment statement, the discard can't be used in code.

function MyFunc(x as int, additionalResult out int) as logic
    ...
    return true

function MyFunc(x as int) as logic
    local additionalResult as int
    return MyFunc(x, out additionalResult)

but I will put it on the list

The only problem that I see is that some people may have already used the single underscore as variable name.
