It is kind of naive, in a discussion relevant to Sage, to talk about
mathematical functions being
"implemented" as a checklist. Compare DLMF to (say) the Wolfram functions
web site.
When you say F is "implemented", does that mean numerical evaluation for
double-precision float arguments? How about arbitrary precision? How about
integration of F(x) and expressions involving it? How about derivatives?
How about addition formulas and relations with other functions?
Its sort of like comparing geographical locations and having a checklist:
US France Italy Antarctica
