Class Description

                        Python expression eval result
                        =============================

 Transport class for bringing objects from python (dynamically typed) to CINT
 (statically typed). It is best to immediately cast a TPyReturn to the real
 type, either implicitly (for builtin types) or explicitly (through a void*
 cast for pointers to ROOT objects).

 Examples:

  root [0] TBrowser* b = (void*)TPython::Eval( "ROOT.TBrowser()" );
  root [1] int i = TPython::Eval( "1+1" );
  root [2] i
  (int)2
  root [3] double d = TPython::Eval( "1+3.1415" );
  root [4] d
  (double)4.14150000000000063e+00

TPyReturn()
 Construct a TPyReturn object from Py_None.

TPyReturn( PyObject* pyobject )
 Construct a TPyReturn from a python object. The python object may represent
 a ROOT object. Steals reference to given python object.

TPyReturn( const TPyReturn& other )
 Copy constructor. Applies python object reference counting.

~TPyReturn()
 Destructor. Reference counting for the held python object is in effect.
