Hi,
I have a class `Image`, and I have a function called
`getSubImage(Rect bounds)`. What I can't figure out is how to
get the result of `getSubImage()` to take on the constness of
the backing image.
ie.
//The Image class is really just a view over a buffer
that's managed elsewhere
const(Image).getSubImage(...) -> const(Image)
Image.getSubImage(...) -> Image
I tried to do this with `inout`, but that requires that a
parameter in the function be `inout`. I don't suppose I could
somehow declare `this` to be inout?
Thanks
I am aware that you can duplicate the method, but it seems a bit
unwieldy and excessive.
