• I have searched the existing issues via is:issue in:title "Illegal IR"
• I have tried using the latest released version of Numba (numba==0.59.1)
• I have included a self contained code sample to reproduce the problem.

del is not supported - I see we don't list it as supported, but we also don't list it as unsupported - in #9593 I've added a note that it is unsupported.
