I have two char arrays at the size of 16KB. I will copy a part of
data between them again and again.
arrayA[0 .. dataLen] = arrayB[0 .. dataLen];
Does the compiler generate code that uses SIMD operations
(128-bits memory copy) automatically, or do I need to do anything
special for this?

not only that. constantly allocating big chunks of memory will inevitably
lead to OOM due to current GC design. you can check it with manual

The GC can't handle that.

Hi,
if I want to clean up inside a signal handler and then exit the

Can I exit() inside a signal handler or should I use a more

To be pedantic, you mean *objects* of different types. (Class is the type.)

if you'll take a look into druntime sources, you'll find that string is
just an alias to `immutable(char)[]`. so you actually doing thing:

Can I not do this cast because it's immutable?
I'm trying to create a template function that can take in any
type of array and convert it to a ubyte array. I'm not concerned
with endianness at the moment, but I ran into a roadblock when
trying to do this with strings. It already works with ints,
chars, etc.
Here's the relevant test code:

Yes, but you can easily detect that by adding a magic number and packet

In pointer arithmetic, the increment value means "that many *objects*
away", not "than many bytes away".
Since id.offsetof is 4, you are calculating 4 MessageBase objects away
(4*8==32 bytes away).
