When an implicit array is used in a write, is causes the whole
expression to become a statement. For example:
```ruby
a = *b
a = 1, 2, 3
```
Even though these expressions are exactly equivalent to their
explicit array counterparts:
```ruby
a = [*b]
a = [1, 2, 3]
```
As such, these expressions cannot be joined with other expressions
by operators or modifiers except if, unless, while, until, or
rescue.
