I got the following output using my student-version of Mathematica: ---- In[1]:=SetAttributes[j,HoldAll] In[2]:=j[1,Unevaluated[2],3,4,5] Out[2]=j[1,Unevaluated[2],3,4,5] In[3]:=j[1,Unevaluated[2],3,Sequence[4,5]] Out[3]=j[1,2,3,4,5] In[4]:=$Version Out[4]="Microsoft Windows 3.0 (April 25, 1997)" ---- Can anybody reproduce this with Mathematica version 4? I don't understand why the Unevaluated-wrapper isn't stripped in the first case too. Maybe not an important problem, but it looks like a bug too me... -- Stig Sandnes University of Oslo, Norway
