wtf is lifetime?

The lifetime repository is a project written in the D programming language, but its README doesn't provide any description of what the project actually does. With no documentation available, it's impossible to determine its purpose or intended audience from the repository alone. The name "lifetime" might suggest the project deals with tracking the duration of something, perhaps memory lifetimes, session lifetimes, or some kind of time-based measurement, but that's purely speculation. The D language is often used for systems programming, so it could be a low-level utility, but without any README content, there's no way to confirm this. Anyone interested in understanding the project would need to look directly at the source code to figure out what it does, how it works, and whether it's useful for their needs. The README doesn't go into detail on any aspect of the project, not installation, usage, features, or examples. For now, this is one of those repositories where the code speaks for itself, and potential users will need to read the D source files directly to understand its functionality and whether it's relevant to what they're working on.
