Below, I just give examples of @fif_codegen tag:
* a pattern can be single-line (after the tag), or multi-line, surrounded with """
* there may be multiple @fif_codegen, they all will be checked
* identation (spaces) is not checked intentionally
* "..." means any number of any lines
* lines not divided with "..." are expected to be consecutive in fif output
* //comments can be omitted, but if present, they are also expected to be equal
* there is also a tag @fif_codegen_avoid to check a pattern does not occur
