@mhd @drmorr If you want or need to be verbose, you can say the following in #Perl to get the number of elements in an array:

```
scalar @array
```

What that does is force an expression into a scalar context.

But a lot of the time you *don’t* need to do that. For instance, this will do the right thing:

```
$length = @array;
```

As well as this:

```
say 'There are four lights' if @lights == 4;
```
