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;
