In Mathematica 10.0.1 this works:
Extract[{a, b, c, d, e}, {{{1, 3}}, {{5, 4}}, {{2}}}]
{{a, c}, {e, d}, {b}}
In Mathematica 7.0.1 it does not. In which version was this syntax introduced?

$\begingroup$ @belisarius Thanks! Since I am not aware of any release between 7.0.1 and 8.0.0 I think I have my answer. Would you consider posting that as such? I think this could be a useful reference for others. $\endgroup$– Mr.WizardCommented Oct 27, 2014 at 16:55

I have Mma v.8.0.0 here and it works and gives the same result as v10.
Just as a reference, it works also on v9.0.1.
IDK if there are versions between 7.0.1 and 8.0.0, though.

$\begingroup$ The revision history says that there are no public versions between 7.0.1 and 8.0.0 so I am accepting this. $\endgroup$ Commented Oct 27, 2014 at 17:27
