Perfectly right, because i read on a MacRuby web page
(http://www.macruby.org/documentation/overview.html) :

Primitives Classes
The primitive Ruby classes (String, Array, and Hash) have been
re-implemented on top of their Cocoa equivalents (respectively,
NSString, NSArray, and NSDictionary).

As an example, String is no longer a class, but a pointer (alias) to
NSMutableString. All strings in MacRuby are genuine Cocoa strings and
can be passed (without conversion) to underlying C or Objective-C APIs
that expect Cocoa strings.

The whole String interface was re-implemented on top of NSString. This
means that you can call any method of String on any Cocoa string.
Because Cocoa strings can be either mutable and immutable, if you try to
call a method that is supposed to modify its receiver on an immutable
string, a runtime exception will be raised.
