           Summary: regression(DMD 2.059head) Wrong error on forward
                    reference to 'front' with -property switch
           Product: D
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: rejects-valid
          Severity: regression
          Priority: P2
         Component: DMD
        AssignedTo: nobody@puremagic.com
        ReportedBy: timon.gehr@gmx.ch

The following code does not compile with DMD 2.059head, when passed the -property switch.

int[] array;
pragma(msg, typeof(array.front));
@property ref T front(T)(T[] a){return a[0];}

Moving the declaration of front to the top fixes the error. This was reduced from a template matching failure (std.algorithm.canFind cannot be instantiated with built-in array types).

The same code compiles fine with DMD 2.058.


Another manifestation of what looks like the same issue:
pragma(msg, typeof(x)); // prints 'int' instead of 'const(int)'
const int x;

The second issue is not the same and isn't a regression.

OK. Reposted as issue 7846.

The code this was reduced from still does not compile with -property for the same reason. I will try to create another reduced example and then reopen the issue.

These snippets still expose the buggy behavior even after the fix:
---
int[] array;
pragma(msg, typeof(array.front));
@property int front(int[] a){return a[0];}
---
---
import std.algorithm;
alias find!("a == b",int[],int) test;
---

I assume it is the same bug in both cases.
