[cpp.module] (original) (raw)
15 Preprocessing directives [cpp]
15.4 Module directive [cpp.module]
A pp-module shall not appear in a context where moduleor (if it is the first token of the pp-module) exportis an identifier defined as an object-like macro.
Any preprocessing tokens after the module preprocessing token in the module directive are processed just as in normal text.
[Note 1:
Each identifier currently defined as a macro name is replaced by its replacement list of preprocessing tokens.
— _end note_]
The module and export (if it exists) preprocessing tokens are replaced by the module-keyword and_export-keyword_ preprocessing tokens respectively.
[Note 2:
This makes the line no longer a directive so it is not removed at the end of phase 4.
