Pragmas are a way to embed programs for the parser in the file being parsed.

I hope the BDFL has the good sense to run screaming from anything that has the word "pragma" in it. As this discussion demonstrates, it's far too fuzzy and open-ended a concept -- nobody can agree on what sort of thing a pragma is supposed to be.

It is a good idea, however, to claim a piece of syntactic turf as early as possible so that if/when it is needed, it is unlikely to cause problems with previously written code. My preference would be to introduce a reserved word 'directive' for future expansion here. 'pragma' has connotations of 'ignorable compiler hint' but most of the proposed compiler directives will cause incorrect behaviour if ignored.

The objectives the "pragma" statement follows should be clear by now. If it's just the word itself that's bugging you, then we can have a separate discussion on that. Perhaps "assume" or "declare" would be a better candidates. We need some kind of logic of this sort in Python. Otherhwise important features like source code encoding will not be possible. As I said before, I'm not advertising adding compiler programs to Python, just a simple way of passing information for the compiler. -- Marc-Andre Lemburg ______________________________________________________________________ Business: http://www.lemburg.com/ Python Pages: http://www.lemburg.com/python/
