High MathGroup,

I tried to evaluate with Mathematica 3.0.1 the following cell:

Limit[Arg[-1+I/n],n->Infinity]

the output was 0! But

Arg[-1] returns Pi

and after loading the package Limit

<<Calculus`Limit`

the same cell Limit[Arg[-1+I/n],n->Infinity] correctly returns Pi, not
0. Is this a bug? The 2.2 did not return this initial wrong result
saying it was not able to calculate this limit without the package.

Best Regards
