> But as you see, `gamma_incomplete` isn't defined in Sage either, but the
table `sage.symbolic.pynac.symbol_table['maxima']` lists the Sage
equivalent `gamma`. Anyway, it should be possible to have the maxima
interface (with the help of maxima itself) rewrite any exponential
integral that Sage doesn't have in terms of gamma functions.
Incomplete gamma is defined in Sage. You can access it directly though
`incomplete_gamma()` or `gamma_inc()`. The top level function `gamma()`
behaves like incomplete gamma if you give it two arguments. IIRC, this is
similar to maple.

working on it currently?
I am not working on it. The ticket status `assigned` is supposed to
indicate that the owner is working on the problem, but we don't use that
much either.
