limit of lambert_w



Dear Maxima-list,

I know from theory that the limit of

(lambert_w(u*exp(u))  + 1) / (u + 1)

as u approaches -1 from the right (left) is +1 (-1).

Mathematica knows this. Maple knows this. But Maxima doesn't seem to
know this. I am familiar with the Maxima FAQ that says "limits might
not be what you expect", but I am wondering if there is something
undocumented or an approach that I do not know that would give the
correct answer.

If not, that's OK; Maxima already rocks.

Best,
Jay
