Dear Group,
Could anybody help me in understanding this
obviously strange behaviour
In[22]:=$Version
Out[22]="4.0 for Linux (April 21, 1999)"
In[23]:=ReplaceAll[Element[Alternatives[a, b], Reals], Alternatives -> List]
Out[23]=(a | b) \[Element] Reals
Why not replaced ??? Compare:
In[24]:=ReplaceAll[El[Alternatives[a, b], Reals], Alternatives -> List]
Out[24]=El[{a, b}, Reals]
As expected
