Increasing the sizes of an array has always given me the shivers, as
beautiful as it is.
Could someone explain why this code behaves the way it does?
string s = "1234";
s.length = 7;
writefln("\"%s\"", s);
prints: "1234���"
Given that it makes no sense to extend a const-size array, shouldn't
there be a run-time check on the new size of the array, so that it
throws whenever it's bigger than the current size?
Also, another issue:
Let's say you have an array that you dynamically resize (meaning you
grow and shrink it a lot of times). In fact, let's say you have:
int[] arr = new int[1024 * 1024];
and then you decide, hey, that's too big for how much space I
actually needed:
arr.length = 5;
Can the rest of the array be garbage collected?
a. If the answer is "yes", then how does the GC know?
b. If the answer is "no", then doesn't that:
(1) Mean that we can have memory leaks?
(2) Mean that we still need an ArrayList!(T) type?
(Note that using Array!(T) does _NOT_ help here, because it can't
hold object references due to garbage collection issues.)
