TIL that std::shared_ptr has a custom "deleter" function you can set for actually deleting the memory. Seems to make for a pretty nice way to create a memory buffer manager. I need to shuffle a lot of smallish buffers and allocating/freeing memory all the time is not particularly efficient, especially not when time is essential. I guess this is nothing new to the veterans out there, but it'll make my life easier.

クラステンプレート ```std::enable_shared_from_this``` とは、```std::shared_ptr``` で所有権を管理している場合、これを継承するとインスタンス自身から ```shared_ptr`...
