A nice remark about the bug! I fully agree with you.

This behaviour certainly takes place in Mathematica 5.0.1.

In my copy of Mathematica 5.1 I see

In[1] := $Version

Out[1] = 5.1 for Microsoft Windows (October 25, 2004)

In[2] := Limit[(3^x + 5^x)^(1/x), x -> DirectedInfinity[-I + 1]]

Out[2] = 5

without any warnings.

RJF> It depends on which "infinity" you mean. Or MuPAD means.

Actually, as for MuPAD, by "infinity" it always understands
Mathematica's "Infinity" / "DirectedInfinity[1]", Maxima's "inf",
Derive's "inf", Axiom's "%plusInfinity" etc.
