If I were to define a write property for arrays foo that takes an int arg, none of the following prototypes work:

main code:
int[] x;
x.foo = 1;

test cases:
@property void foo(T)(T[] arr, int x) {}
or
void foo(T)(T[] arr, int x) {}

outputs:
testbug.d(10): Error: template testbug.foo(T) does not match any function
template declaration
testbug.d(10): Error: template testbug.foo(T) cannot deduce template function
from argument types !()(int[])
testbug.d(10): Error: x.foo is not an lvalue

test case:
@property void foo(int[] arr, int x) {}

outputs:
testbug.d(4): Error: properties can only have zero or one parameter

test case:
void foo(int[] arr, int x) {}

outputs:
testbug.d(10): Error: function testbug.foo (int[] arr, int x) is not callable
using argument types (int[])
testbug.d(10): Error: expected 2 function arguments, not 1
testbug.d(10): Error: x.foo is not an lvalue
testbug.d(10): Error: cannot implicitly convert expression (1) of type int to
void

I think at least the two variations that use @property should work.  They are pretty unambiguous.

This is blocking my work on the array pre-allocate patch.

Downgrading severity.  This is no longer blocking the array append work, since it was determined that a property was not the best syntax.

I still think this should work.
