Such duplicating in common case is not good idea (but could optimal
option in case of Calculate modules). Anyway what about creating libmath
(or so) and patch Speak (at least) and Calculate to use this lib.
In case of Speak, it is already using 0sugar dependecies. You can create
separate project on git like libjournal. Only "libmath" string will be
added to  to use libmath in Speak. 0sugar is not yet ready for
broad usage but it can work in case of libmath.
