In[1]:=
Table[Unevaluated[Sequence[{X[C][i],Y[C][i]}]],{i,4}]~~
Prepend~~"Corner (Geometric) Variable"
Out[1]=
{{X[C][1],Y[C][1]},{X[C][2],Y[C][2]},{X[C][3],Y[C][3]},{X[C][4],
Y[C][4]}}~~Prepend~~Corner (Geometric) Variable
I expected the result of the following command, because the two forms
of input should parse to an identical expression, AFAIK:
In[2]:=
Prepend[Table[
Unevaluated[Sequence[{X[C][i],Y[C][i]}]],{i,
4}],"Corner (Geometric) Variable"]
Out[2]=
{Corner (Geometric) Variable,{X[C][1],Y[C][1]},{X[C][2],Y[C][2]},{X[C][3],
Y[C][3]},{X[C][4],Y[C][4]}}
What's wrong?
