urnathan added a comment. I can;t really tell what you're doing. C++20 lexes import (&module) declarations as preprocessor directives. the parser must also recognize only such declarations that came through from lexing such directives. It is unrelated to #import. GCC's implementation drops the preprocessor into directive mode if it sees 'module' or 'import' (optionally preceeded by 'export') at the start of a line[1]. Those keywords are converted to unspellable internal tokens that the parser recognizes to parse module and import declarations. An end-of-pragma token is injected at the end-of-line, and again the parser expects that after the terminating ';'. (it's leveraging the pragma machinery)
[1] it also peeks the next non-white-space token for '<', '", or <begin-identifier-char>, as specified in the std. occurrences of 'module' and 'import' that are not lexed that way go through as regular identifier tokens, not keywords.
