Tuple assigments fail in short-circuit evaluations

``` julia
begin
	# valid
	x,y = 1,1
	# valid
	x,y  = (2,2)
	# valid
	true && (x,y = (3,3) )
	# invalid
	true && (x,y = 4,4)
end
```

The last assignment gives the following error:

```
ERROR: syntax: invalid named tuple element "4"
```

I don't think this is the intended parsing behavior.

Tested on 1.11.1 on Linux/amd64.
