The data constructed by this call remains in the 'C-alloc' realm, i.e. it can be `MEM_dupallocN`'ed, and `MEM_freeN`'ed. This is intended as a temporary API only, to facilitate transition to full C++ handling of data in Blender. It's primary target is to allow pseudo-POD types to use default values for their members. See e.g. !134531. Unlike !143827 and !138829, it does not change the current rule (`new` must be paired with `delete`, and `alloc` must be paired with `free`). Instead, it defines an explicit and temporary API to allow a very limited form of construction to happen on C-allocated data, provided that the type is default-constructible, and remains trivial after construction. ### Notes * The new API is purposely as restrictive as possible, trying to only allow the current known needs (init with default member values). This can easily be extended if needed. * To try to stay as close as malloc/calloc behavior as possible, and avoid the 'zero-initialization' gotcha, it does not use value-initialization, but instead default-initialization on zero- initialized memory. _Ideally it would even not allow any user-defined default constructor, but this does not seem simple to detect._ Pull Request: https://projects.blender.org/blender/blender/pulls/144141
