push_back(seq, t);

<<<<<<< .working Return type: A model of Forward Sequence. ======= Return type: >>>>>>> .merge-right.r57242

Semantics: Returns a new sequence, containing all the elements of seq, and new element t appended to the beginning. The elements are in the same order as they were in seq.
