burgled-batteries3 provides a shim between Python3 (specifically, the CPython
implementation of Python) and Common Lisp.
CLPython is great when it works. However, if you’re using a low-resource computer—perhaps an underpowered VPS, or a Linux box salvaged from the 90s—, or need access to a Python library written in C, or there’s a bug and you can’t be bothered to narrow it down to a small test case, CLPython can’t help you. Two out of three of those are more your problem than CLPython’s, but hey, I’m not here to judge.
