I am afraid not... But I do not see what kind of function is not writable in 
the language but more easilly in C...

If you mean to impose conditions such as T^4+dnu(T) = g, this has already be 
successfuly done with ff3d: you just need to write
        T(n+1)*T(n)^3+dnu(T(n)) = g
in ff3d --- going back to standard Robin conditions.

Concerning external functions/modules. This is not something that will be 
implemented soon. Many other functionnalities are to be fixed or added 
before.

Since you have the sources, you can add your own function in the language 
copying what was done for abs,log,...

I hope that answers to your question.

Best Regards,
Stephane.
