Carefully reading and testing the examples in "Learn to Tango with D"
made me stumble across a few things I did not quite understand. A
internet search revealed:
Errata for 'Learn to Tango with D'
(http://www.dsource.org/projects/dallegro/wiki/TangoBookErrata)
That explained a few "confusing" things.
But there is still one entry I think is a typo, but I'd like to ask
the programmers here, if it is indeed a "bug".
On p33, Slicing, these examples are given.
---
int x[] = [0,1,2,3,4];
int y[] = x[1..x.length];
int z[];
z = x[1..x.length-1];
int all = x[]; // all is a view of all of x, from the first //L13
// element to the last, i.e., 0, 1, 2, 3, 4.
---
To me the last line makes no sense, it should read:
int all[] = x[];
and dmd v1.030 agrees. The code from the book yields a compile error:
Error: p33_slice_test.d(13): Error: cannot implicitly convert
expression (x[]) of type int[] to int
So is it indeed a bug?
(I'll be posting the other questions in this thread, later on.)
