Thank you!

It was copy+paste from std.typecons Nullable!
Cleaned it up.
Strange thing: this code doesn't work for me if _value is 
protected - somewhere in CTFE generated code. "_value is 
unaccessible" It's hard to define exact place where it fails 
(inside of mixin).
Tried to write different code which uses String with private 
_value, but cannot reproduce the same error. Leaving public 
_value so far.
