context should be orthometric

[ssqq]

Because the context is global, so the dictionary implemented with factor is global constants variable. any module which use factor would  pollute other modules namespace. any list or string implements with factor which could pass reference to function also is global variable, It has same problem when loaded to other module.  



I think context should be designed to nested:

Code Select Expand

(context 'namespace)
(context 'namespace:subnamespace)

then we could implement local factor.
