156 The binary representation of modules is automatically generated by the compiler on an as-needed basis. When a module is imported (e.g., by an ``#include`` of one of the module's headers), the compiler will spawn a second instance of itself [#]_, with a fresh preprocessing context [#]_, to parse just the headers in that module. The resulting Abstract Syntax Tree (AST) is then persisted into the binary representation of the module that is then loaded into translation unit where the module import was encountered.
158 The binary representation of modules is persisted in the *module cache*. Imports of a module will first query the module cache and, if a binary representation of the required module is already available, will load that representation directly. Thus, a module's headers will only be parsed once per language configuration, rather than once per translation unit that uses the module.
