lists in scalar/boolean context return the number of their elements.
Oh. Once again, trying to dispel the myth of that statement.
Repeat after me:
- You can never have a list in a scalar context...
- You can never have a list in a scalar context...
- You can never have a list in a scalar context...
Now, what's really happening is that you have a list assignment operator
in a scalar context, which is defined as having a return value of the number
of elements copied across, while giving a list context to the right side.
In this case, the right side is a simple expression, which gets turned into a list
of one element. So we get a "1" for the return value.
Once more, just so you remember:
- You can never have a list in a scalar context...
