You're correct that 'a'.'b' is a constant expression, but I wouldn't call 'ab' 
a constant value, it's a literal [1]. While "constant value" makes logical 
sense there is a long history of agreed terminology for these things and you 
will find that using it will enable smoother communication with fellow 

Initial values of class constants and member variables must be literals as they 
are defined not evaluated.
