I agree 1000% things are confusing when you want to manage memory 
yourself, you either have to check every functions and see if 
they allocate or no, or force yourself to add @nogc everywhere

OR use @betterC and have access to no std at all

I personally picked the @betterC option and use D like i'd use 
C/C++, and it feels much better, i have my own Allocator struct, 
and whenever i need to allocate memory, i ask for an allocator

If only the std was designed like this, whenever you want to 
allocate, you ask user to provide an allocator

Want use GC? use gc allocator, everyone wins
