          Issue ID: 14735
           Summary: [REG2.068-b1] std.string.indexOf cannot deduce
                    function for char argument
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: pro.mathias.lang at gmail.com

The following code compiled fine in 2.067:
```
void main()
{
  import std.string;
  enum Test = "Hello\0World";
  char[64] foo;
  foo[0 .. Test.length] = Test[];
  auto greetings = foo[0 .. foo[].indexOf('\0')];
}
```

But now it outputs:

Error: template std.string.indexOf cannot deduce function from argument types

= CaseSensitive.yes) if (isForwardRange!Range &&

&& isSomeChar!Char2)


This affects Vibe.d
