[C++-sig] detecting if a function is written in python or C++

[Pierre Barbier de Reuille]

Hello,

je me rends compte que je t'ai répondu mais j'ai pas mis la réponse pour
la ML ... comme j'étais sur le webmail de mon labo j'ai plus de trace du
mail ... tu pourrais le forwarder sur la ML s'il te plait ?

Merci,

Pierre
