Thanks.  I'm sorry about the long delay in reviewing this.

Yeah, and Pascal.

I think that if there is no choice arising from the language (I don't
know Fortran) then it is up to you.

I don't think we should introduce uses of current_language into this code.
It should probably just be an argument.
