Bug 22417 – Slice assignment operator overloading example is incorrect

The example in the language spec under "Slice Assignment Operator Overloading" [1] is incorrect. Specifically, it claims that the following rewrite is performed: --- a[3..4] = v; // same as a.opIndexAssign(v, a.opSlice(3,4)); --- However, using the -vcg-ast compiler switch reveals that this statement is actually rewritten as follows: --- a.opSlice(3LU, 4LU)[] = v; --- This is because the D2-style opSlice overload is declared incorrectly: it does not accept a `dim` template parameter, as specified in the section on "Slice Operator Overloading" [2], and it returns an `int[2]` rather than the `size_t[2]` expected by the opIndexAssign overload.
