Thank you for the reference.

I read through the postings, but I found the discussion quickly
switched to a discussion of C++ scoping rules rather than the asthetic
or semantic validity of the "this->mem_func()" practice.

Aesthetics.

If you are comparing yourself to "that", then it is natural to refer to
*this as *this;

bool operator != (const String &that) const {return !(*this == that);}

bool operator >= (const String &that) const {return (*this > that) ||
(*this == that);}
bool operator <= (const String &that) const {return (*this < that) ||
(*this == that);}

For new classes where such operators should be defined (the usual six),
I simply cut and paste, rename class name, and move on.

I noticed while debugging yesterday that Microsoft tends to use
"__that" as the name of the second argument in similar circumstances.
I would imagine that they are putting "*this" in their code too.

But I agree that sprinkling it throughout member functions for no other
reason is a bit much.
