Lol, you don't have to load and unload the curl dll.
std.net.curl have its own lazy libcurl loader. But i'm not sure
if it tries to find the dll in the temp directory. If it is the
case, then it simply doesn't unload the dll when you have called
some function from it.

yes, it is allocating memory. you can test such cases with

It is translated to idup.
So yes, it allocates memory.

Don't know if it is fixed.
Exit is not "normal exit" for D programs so, do not use it.
Your threads should stop at some point to make able the app exit
successfully.
There's a "join" method. You can use it with your "done" variable.

Hi !
I can't find this in specs.
If i add an element to AA:
aa[10] = 123;
Will [10] be always the same (of course i don't remove that

Thanks for a reply.
I think specs should be enhanced.

2) Is all the dtors always called when i call destroy ?

there's something wrong with your design. Maybe fibers suit

There's a problem with « dst[0 .. n] = val; ».
It should be « dst[0 .. n][] = val; »
It's because it's implemented in DMD only partly.
There's a bug report associated with it.
I'm writing a game engine in D. Try to minimize allocations and
that's will be OK.
I'm using delegates and all the phobos stuff. I allocate only in
few places at every frame.
So i can reach 1K fps on a complicated scene.
GC is not a problem. DMD optimizes so ugly that all the math is
very,
All types are hashable and for your own structs and classes you
can redefine opHash
Sorry, i meant it gives b == fooo\\nbar
I'm writing an interpreter and it should dump original string
from memory.
Also i wonder if there's a function to convert aaa\\nbb to
aaa\nbb (i.e. to unescape)
Hi ! I wonder how to escape a string in phobos ?
For example
auto a = [ fooo\nbar ];
auto b = format(%(%s%), a);
gives b: fooo\nbar
Is there any other function to escape string? I'm looking for
something that doesn't require to make an array at first.
For example is there string
It's only words.
If we speak about LDC it can compile fast in debug mode with
performance average to DMD's backend but with much great
performance in release mode thanks to vectorization and other
techniques.
Also LDC thanks to LLVM supports X86, X86-64, PowerPC,
PowerPC-64, ARM, Thumb,
Setting up LLVM infrastructure is only needed when you is a LDC
developer.
I think for ordinary users it's not their business.
align doesn't work in DMD. There's bugreport for a long time.
DWORD is an uint.

It's better to return this and have return type ref auto i
think.
Also second question is what are better to use, current template
recursion-based code or rewrite it to CTFE ?

Yes, i know that, but my question isn't about it.
I want to type `pure:` at module's beginning and have all
function(in classes, too) declared as pure.
I think `pure:` should do it. But it doesn't.

Why so ?
And why @nogc not transitive too ?
