--- Comment #44 from Paul Backus <[email protected]> --- (In reply to Nick Treleaven from comment #43) > Note that `if (arr !is null)` is equivalent to `if (arr)`. Those check both > the .ptr and .length fields (i.e. `is null` means exactly the same as `is > []`). To be 100% explicit: both `if (arr !is null)` and `if (arr)` are equivalent to `if (a.ptr || a.length)`. --
