That's no fun!
I'd never see mpmath before, it looks like it is worth investigating.
Nevertheless, I still intend workin

If the result you're expecting is around -1.005, this exit condition
is rather optimistic: the difference between the two Py

This is only peripherally a Python problem, but in case anyone has any
good ideas I'm going to ask it.
I have a routine to calculate an approximation of Lambert's W function,
and then apply a root-finding technique to improve the approximation.
This mostly works well, but sometimes the root-fin
