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 this syntax in Objective-C.
