First，the above strings as it is only work for uint8; while 
binary literals work for all  integer sizes.

Second, why not provide the above "trivial parser" into std lib 
(so nobody need to reinvent the wheel), and ask users use it over 
years to discover unseen problems and get feedback before 
deprecate / remove binary literals?
