make a list of prefix use for functions

•  nf -> number field

•  bnf/rnf

•  is -> boolean functions

•  zn -> Z/nZ

•  ff -> finite fields

•  qf -> quadratic forms

•  mat -> matrices

•  ell -> elliptic curves

•  dir -> dirichlet series

•  ms -> modular symbols

•  pol -> polynomials

•  ser -> series

•  int -> integration

•  sum -> sums

•  vec -> operations on vectors

what is a good prefix ?

•  meaningful

•  short

•  discriminant (should not prefix any existing function)

•  3-4 letters seems appropriate for most packages

suggest appropriate prefix for new families

•  nca -> non commutativ algebras / aal -> associative algebras [ ? ]

•  lfun -> lfunctions [ ? ]
