batch( * , test) and sets

Hello,

I find this puzzling

testsets.mac:
------------------
{1,2,3};
{1,2,3};

is ( {1,2,3} = {1,2,3} );
true;
------------------


(%i1) batch("testsets.mac",test);

********************** Problem 1 ***************
Input:
{1,2,3}

Result:
{1,2,3}

This differed from the expected result:
{1,2,3}

********************** Problem 2 ***************
Input:
is({1,2,3} = {1,2,3})

Result:
true

... Which was correct.

1/2 tests passed.
