Hi,
Restricted is ok, but I like constrained better. Please see:

Thank you very much for the links, they inspired me to think deeply about the design of my class once again :). What I meant to create was pretty similar to constrained_value, only more complex, more general and maybe a little more efficient. BTW, constrained_value of Christofer Diggins has at least one 'bug' - it has a default constructor which default-initialises the value, and doesn't check if this default value conforms to the constraints. I also believe, that it'd be better to supply operator const value() than operator value() - this conversion is implicit so the const version would be safer. Best regards, Robert
