Issue ID: 20673
Summary: Improve error message for opDollar in pointers
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Keywords: diagnostic
Severity: enhancement
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
A very common beginner mistake:
```
void main ()
{
int* ptr;
assert(ptr[0 .. $] == [1, 2, 3]);
}
```
This will yield the following message:
```
diagxxx.d(4): Error: undefined identifier __dollar
```
Not quite as informative as it could be. This could be a good starting task for
someone wanting to touch DMD. The error is produced here:
