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
