This is false. Making a new implementation is a practical purpose. Any new implementation will have to work with the spec, instead of idiosyncracies of other implementations. Ergo there are practical purposes which go by how the language is defined in its specification.

Some languages have more of a proper spec than others, of course. If we look at for example Scheme dialects, then they often change their implementation for better conformance with the various rnrs standards. New Scheme dialects often early on try to conform very much to the standard to avoid issues later on.

Not yet it isn't. At least not for Python. I mean there are plenty of alternative implementations of Python but they aren't practical because they don't work with CPython modules (as far as I know anyway) so approximately nobody uses them. The de facto spec is "what CPython does".

PyPy work well with CPython modules but the performance is not that great, with CFFI performance is really good in PyPY, HPy project will change this https://hpyproject.org/

Last I checked, Pypy wasn’t compatible with many important packages in the Python ecosystem. As of a couple years ago, there was no trustworthy, supported package for talking to a Postgres database with Pypy because psycopg2 wasn’t supported.

I've been using PyPy and psycopg2cffi in production for the last 5-6 years or so without any issues.

https://pypi.org/project/psycopg2cffi/

Interesting. I wasn't able to get that working when I tried several years ago. I forget the specific issue.

When is the last time you checked ?

I have run it with pandas+numpy and postgres+timescale without issue for the last year.

postgresql can work with psycopg2 but is not the same performance as psycopg2cffi , i will integrate some databases to PyPy, and also HPy project will bring any Cython library to PyPy with basically the same performance or better.

I heard that very argument about GCC. C++ without __attribute__ is not practical for embedded development therefore C++ for PLCs is what GCC does. And yet, the general consensus now is that C++ is ISO/IEC 14882, and what GCC does is just an implementation.

With Python, you don't even have to go "alternative" to use LLVM compiler infrastructure. You can use CPython + Numba and compile your kernels for both CPU and GPGPU on the go. Which is very practical.

Which is ironic, to compile a CUDA kernel in C++, you would have to use an alternative NVidia implementation of the language.
