You're quite right, I have proposed it to have an opinion by experts. Indeed I have no knowledge about how a parser works. This is why I asked if this is possible and desirable. Anyway, I was not thinking about a macro system, but about custom keywords. Maybe a macro is more simple, but was not my idea. My idea is to be able to delegate the parsing of a piece of code to a custom parser, defined in a third-party module. Cython, for example, uses its parser to compile Python code to C code. Cython uses custom keywords like cdef to speed up the code introducing C static typing. My idea and question is if it's possible to have something like this: from cython import * @int a = 0 About Jython and other implementations, as far as I know they can't use C extensions. Not without many troubles. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/75N4W2NQMC3LZOPY5TU7357D5YYZO3D3/ Code of Conduct: http://python.org/psf/codeofconduct/
