(C2) taylor(exp(%i*x),x,inf,1);

Error: |$x| is not of type LIST.

True, Inf is an essential singularity for this function, but
(a) it still shouldn't give an internal error and (b) it does
just fine with taylor(exp(x),x,inf,1).

    (%i4) taylor(exp(%i*x), x, inf, 1);
    (%o4)/T/ %i sin(x) + . . . + cos(x) + . . .
