Issue ID: 22200
Summary: it is not specified that `$` yield a rvalue
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1

Reporter: [email protected]
I was curious to see if the following
```
void main()
{
int[] a;
a[++$ - 1] = 0;
}
```
worked. It is not
> /tmp/temp_7F0644F44CF0.d:8:9: Error: cannot modify operator `$`
but given the specifications
> the spec is "Within the [ ] of a static or a dynamic array, the symbol $
> represents the length of the array."
it was not clear that this will fail.
