Define for 0<=x<1 the Lambert series
f[x_] := Sum[ x^n/(1-x^n), {x,1,oo}]
How do I get Mathematica to calculate the first few terms of a series
expansion like
Series[f[x],{x,0,4}] ?
Also a series like
e1[x_] := Sum[x^n/(1+n!), {n,0,oo}]
does not seem to be expandable with Series.
BTW same thing in 8.0 and 5.2

Wolfgang
