dcoder:
Also, is there any surprises / difference between the two:if( !arr.length) and if( arr.empty) do they produce the same thing all the time? thanks.
No surprises here, thankfully. Its implementation: https://raw.github.com/D-Programming-Language/phobos/master/std/array.d @property bool empty(T)(in T[] a) @safe pure nothrow { return !a.length; } In that file I'd like one more function like this: @property bool empty(K, V)(in V[K] a) @safe pure nothrow { return !a.length; } Bye, bearophile
