This is by design. 'const' modifier on ansistring and other 'managed' type arguments instucts the 
compiler to omit refcount changes, yielding a faster code. At the same time it prohibits direct 
modification to the argument, but nothing can be done if you modify another location that aliases 
the argument.
If you need proper refcounting, you should pass the argument by value (i.e. without 'const' modifier).
