+// Notes on swig and this file gdcm.i:

+/////////////////////////////////////
+// Note 1: swig collision of method overloading and %typemap
+// Consider the following junk.i file:
+// %module junk
+// %{
+// #include <string>
+// #include <iostream>
+// void Junk(std::string const & bozo) { std::cout << bozo << std::endl; }
+// void Junk() { std::cout << "Renamed Junk()" << std::endl; }
+// %}
+//
+// %typemap(python, in) std::string const &
+// {
+// $1 = new std::string( PyString_AsString( $input ) );
+// }
+// void Junk();
+// void Junk(std::string const & bozo);
+//
+// that we compile on linux with:
+// swig -c++ -python junk.i
+// g++ -g -I/usr/include/python2.3/ -o junk_wrap.o -c junk_wrap.cxx
+// g++ junk_wrap.o -shared -g -o _junk.so -L/usr/lib/python2.3/config \
+// -lpython2.3
+// and invoque with:
+// python -c 'from junk import *; Junk("aaa") '
+// then we get the following unexpected (for novice) python TypeError:
+// TypeError: No matching function for overloaded 'Junk'
+//
+// This happens because the swig generated code (at least for python) does
+// the following two stage process:
+// 1/ first do a dynamic dispatch ON THE NUMBER OF ARGUMENTS of the overloaded
+// Junk function (the same happens with method of course). [Note that the
+// dispatch is NOT done on the type of the arguments].
+// 2/ second apply the typemap.
+// When the first dynamic dispatch is executed, the swig generated code
+// has no knowledge of the typemap, and thus expects a pointer to a std::string
+// type i.e. an argument to Junk of the form _p_std__int<address>. But this
+// is not what python handles to Junk ! An invocation of the form 'Junk("aaa")'
+// will make Python pass a PyString to swig (and this is precisely why we
+// wrote the typemap). And this will fail....
