Index array with result of overloaded method

What will reproduce the problem?
var Arr:Array of Integer = [0,0];
begin
  Arr[ round(1) ];
end.

What is the expected output? What do you see instead?
Error: Don't know which overloaded method to call with params (Int32) at line 6

Which version are you using?
c96f612e0066    

Please provide any additional information below.
This happens whenever you try to index an array with the result of any 
overloaded method. If methods is not overloaded it works, IE: `Arr[ ceil(1) ]` 
works fine.
