           Summary: Describe hidden value passed to class member functions

          Severity: normal
          Priority: P2

As in C++, D appears to implicitly pass a reference to the class instance into
a call to a member function to support references to class member vars and
"this".

The fact that a hidden var is passed in is documented in reference to nested
classes, but not for basic member functions.

This behavior is likely well known to experienced c++ developers, but needs to
be documented in a language spec.

I ran into this trying to pass a class member function into
std.algorithm.lowerBound, which of course doesn't work because of the hidden
class reference.  (There needs to be a way to pass a member function in easily
- subject for another bug).
