// All declarations labelled as `pub` (for public) will end up in this struct type, ready for use.

// `@import("std")` is a special case in the compiler, and gives you access to the standard library.
// Other `@import`s will take in a file path, or a package name (more on packages in a later chapter).
// We will explore more of the standard library in later chapters.
