Maybe its too advanced for me as a beginner now its just I am curious over the usage and applications with a simple hello world like example explaining what this library will accomplish. I asked it previously at https://www.reddit.com/r/programming/comments/4hti33/dconf_2016_is_streaming_right_now/d2satic/ but still I don't understand the exact applications of the same.

I also have found std.experimental.allocator's documentation is 
written at quite the advanced level. There is definitely scope 
for someone to improve it (for instance, the main page 
presupposes that the reader already knows what allocators are) or 
write a nice tutorial.

Nevertheless, the building blocks page is actually about how to 
build your own allocator. You can use std.experimental.allocator 
without building your own. The page
https://dlang.org/phobos/std_experimental_allocator.html
actually has some very simple examples on how to allocate an int 
or an array and dispose of them.
