This forces going direct to iterative solver rather than first trying and failing with bisection solver.

You might want to mention guess of 0 will iterate for W0(x), i.e. principle branch. (*)

(*) Assumed W0 is not complex (x ≥ -1/e), see comment below.

Thanks for pointing that out. I want to retain the secondary branch result when 0 >x ≥ -1/e so I've removed the initial guess on my prime.
