namic Python, those problems go away because the type notation would not be valid Python code. In the integrated approach, type checking built in, there would still be overhead but it would be *useful* overhead doing the actual type checking. -- cheers, Hugh Fisher __

[Python-Dev] Re: Typing syntax and ecosystem, take 2

dvantage is that the Python interpreter does not need to know about typing, so no PEP 543 and no PEP 649, which is currently generating a lot of esoteric (to me) discussion on python-dev. > Please do not take these comments personally, in a verbal setting I would try

integrated into CPython itself. An alternative is the TypeScript/JavaScript model, where typed Python becomes a distinct programming language that cannot be executed directly by the Python interpreter. -- cheers, Hugh Fisher ___ Py

[Python-Dev] Re: Typing syntax and ecosystem

away before running an interpreter which reads the same source, scans into lexical tokens, builds an abstract syntax tree, and executes. On the purely pragmatic level there is an extra chance for mismatches and things to go wrong; and from an environmental viewpoint it isn't a great use of resources.

jects! So now "const" in C++ for objects just means you don't intend to change the internal state, but it might do so anyway. Again, I can see a case in embedded systems for "const" meaning "this can be put in ROM". But I don't think that use case is co

r the language reference, use the license plate or registration analogy to introduce "handle" and after that use handle throughout. It's short, distinctive, and either will match up with what the programmer already knows or won't clash if or when they encounter handles els

Re: [Python-Dev] C99

d MSVC have different ideas about how inline functions in C work. Are they static or extern? Do you need provide an implementation body somewhere? There are also differences between the C++ and C99 definitions. Probably all solvable with build settings, but not as easy as one li
