--- Comment #3 from emsr at gcc dot gnu.org --- N.B. This 'bug' and the patches apply both to the 'regular' Laguerre polynomial laguerre(n,x) and to the associated Laguerre polynomial assoc_laguerre(n,m,x). Note that this gets rid of a throw or two. The mandated special function throws should become preconditions anyway. Later. Furthermore, if the not-so-special functions like pow, exp, sin, etc. can be constexpr then these can be too. Later.
