provide it - you do not need an opAssign at all, as your

The example below prints:

Here is a strong statement:

I think the safest thing you can do is:
void oldAssign(Type rhs)

this.tupleof = rhs.tupleof;

The online documentation _is_ the official spec, though it definitely doesn't
have enough detail to be unambiguous, and in some cases, it's not properly up-
to-date.

When I define an opAssign, I'm not really overriding a default
opAssign, because there is none, instead I'm overriding the
default behavior which is to perform a memcopy-like operation.
So if I defined an opAssign function, but for some odd reason I

I assume that when I define an opAssign, only the opAssign that I

I may be thoroughly confused at this point. Is there both a blit
and a postblit, and an optional opAssign that when specified will

postlbit is making a new copy of an object, whereas opAssign is replacing the
state of a pre-existing object. The
AFAIK, opAssign and postblit are different operators. Postblit is
called after blit, and opAssign is called instead of blit.

My understanding is that a struct will have a default postblit
opAssign. What I want to know is if I can call the default
opAssign after overriding it, or is it inaccessible?
I know that I do not have to execute the default after
overriding, but if I can call it, I'd like to know because in
