Why would it? They're different types. Their elements happen to have the
same size, but that doesn't mean that they're used for

When T is `const int`, the above code declares and initializes a
constant variable:

const int candidate = const int(5);

I've not used static constructors before, but it seems like the
following should not be allowed:

x.writeln(); // 5

x++;
assert(x == 7);

Should I file a bug to

Yes, it's a bug. It's a clear violation of the type system if a
non-mutable variable is ever given a value more than once. It
should be initialized, and then it should be treated as illegal
to ever assign to it - or to do

Nevermind. It turns out this was because the call to the Unit
destructor was missing in `Map.deleteUnit`. The segfault happens
