Summary: Self-assigned variable expression with no effect
doesn't have compiler error
Product: D
Version: unspecified

OS/Version: All
Status: NEW
Severity: normal

Reduced example:
void main()
{
int i;
i = i;
}
The code `i = i;` does nothing, but there are no compiler error.
This error in real life:

Note that we already have errors for no effect expression, for example for this
code: `int i; i;` - `Error: var has no effect in expression (i)`.
