Lambert function and Wolfram or "±infinity+i×K=±infinity" ?

[Gil]

Thanks again, Albert, for the time you always take to answer our posts or questions, always trying to develop clean and detailed arguments or solutions.

Sometimes even too technical posts with your program Lua, sometimes only you answering your own commentaries!

But great, and always nice written.

Congratulations for partaking your knowledge and valuable time.

Really amazing — and very much appreciated.
