A library follows. (i wanne hear 'thank you' .. 
All you have to do now, is call either register_function or register_procedure
tell the routine-id and those of its parameters
and you're done.

--- whatyouwant.e

sequence rtypes, rdata

global procedure register_function (integer rp, sequence rd)
    if rp > length(rtypes) then
        rtypes &= repeat (-1,  rp-length(types) )
        rdata &= repeat ("", rp-length(types) )
    end if
    rtypes[rp] = R_FUNCTION
    rdata[rp] = rd
end procedure

global procedure register_function (integer rp, sequence rd)
    if rp > length(rtypes) then
        rtypes &= repeat (-1,  rp-length(types) )
        rdata &= repeat ("", rp-length(types) )
    end if
    rtypes[rp] = R_PROCEDURE
    rdata[rp] = rd
end procedure

global function routine_info (integer rp)
    if rp > length(rtypes) then
        return -1
    elsif rtype[rp] != -1 then
        return {rtypes[rp], rdata[rp]}
    else
        return -1
    end if
end function
