I actually donated to the Pypy project in the past but I don’t use it.

Two reasons for my hesitation:

1) Cpython is fast enough for most things I need to do. The speed improvement from Pypy is either not enough or not necessary.

2) Lingering doubts about subtle incompatibility (in terms of library support) that I might have to spend hours getting to the bottom of.

I already work long hours and don’t have bandwidth to tinker. With Cpython, although slow, I can be assured is the standard surface that everyone targets, and I can google solutions for.

It’s the subtle things that i waste a lot of time on. It’s analogous to an Ubuntu user trying to use Red Hat. They’re both Linuxes but the way things are done are different enough that they trip you up.

The only way to get out of this quandary is for Pypy to be a first class citizen. Guido will never endorse this so this means a bunch of us will always have hesitation putting it into production systems.
