I will buy a beer to anyone who implements a good fast 2nd order linear-chain CRF in an imperative lang like C++/Julia/Cython/Python+Numba. Many many models would benefit from higher order information. My current implementation is slowish and the fast ones like crfsuite are only 1st order. FlexCRF is buggy. There are literally no good 2nd order CRF libs.
