At
https://github.com/nordlow/justd/blob/master/algorithm_ex.d#L43
I've implemented a function either() with behaviour similar to
the `or` function/operator in dynamic languages such as Python
and Lisp.
I'm almost satisified with it except that the lazy evaluation at
https://github.com/nordlow/justd/blob/master/algorithm_ex.d#L45
cannot be made nothrow.
If I qualify the function as nothrow DMD complains as
algorithm_ex.d(45,16): Error: 'a' is not nothrow
algorithm_ex.d(46,29): Error: '_param_1' is not nothrow
I don't see a reason why any of these two cases should throw.
The same problem occurs if I make the implementation use only one
function and check the recursion termination case with `static if
(bs.length == 1)` instead.
Is there a workaround for this?
