getcwd() doesn't work during compile time because it's a system call.

It is the () at the end of a thing. You can overload it in a

Just wondering why compiling the following fails with the -debug
switch, but appears to compile and execute fine without it:

import std.container;
int main(string[] args) {
Array!string letters = [b,a,c];
sort(letters[]);
writeln
would someone care to work on updating this? I understand from
Daniel's post in main list that the only thing that doesn't work
is special member functions. that's different from what the
documents say, and it is surely something important for D that
people are aware of this.
I don't

Yes, when they are declared right at the scope, and not contained

Ok that's great thank you.
It's quite hard trying to get a proper understanding of memory
allocation in D after years of C++ / RAII / unique_ptr /
shared_ptr . I understand the details of course but it's going to
take a while to really know it.
Is there any way to explicitly free a dynamic
Thanks again for the updates. I've experimented some more and

To be honest I'm finding it very hard to find the right idioms in

Your use of @trusted is wrong and dangerous.
Ok thank you.
Seems to me that there is enough doubt that this is supported
that I'd be best to avoid relying on it, or at least ensure that
it's all encapsulated in something I can easily change.
