D has opAssign, making defining implicit conversions from any type to a

//conversions from string part of the definitions of Data, Data2

Hmmm... very interesting. I was thinking of the same these days because
we have qualifier(T[]) automatically change to qualifier(T)[] upon
passing to a function. However, there is no way for the user to specify
such type change for a user-defined type.
Adding some sort of opPass would help solve the current problem we have
with passing const ranges into functions. (Currently they won't work
unless they're built-in slices).
