9.9.2 C99-Like Fast Enumeration Syntax ¶

A c99-like declaration syntax is also allowed:

  id array = …;  for (id object in array)  {    /* Do something with 'object'  */  }

this is completely equivalent to:

  id array = …;  {    id object;    for (object in array)    {      /* Do something with 'object'  */    }  }

but can save some typing.

Note that the option-std=c99 is not required to allow thissyntax in Objective-C.
