To STL or not to STL, that is the question...

[voidspace]

STL is really nifty tool to make a programmer life easier .. but STL code is hard to maintain and debug.
For example

class AFX_EXT_CLASS CBulletInfoEntry : public CObject
{
DECLARE_SERIAL(CBulletInfoEntry)

public:
int nKey; // the Key: (nRow<< 4 | nCol)
RGBCOLOR nColor;
int nRow;
int nCol;
};

typedef std::set<CBulletInfoEntry> BULLETMAP;

BULLETMAP::iterator it = m_Map.find(Key(iRowl, iCol));
ASSERT(it != m_Map.end()); // the entry should exist

// At this point i want to view the values of 'it' which is basically a item of BULLETMAP and namely CBulletInfoEntry. But I cannot do this in the debug or watch window. This is one debugging difficulty we face when using STL.
i.e it->nCol ?
it->nRow ?

Also I cannot do this in debug window it,10 ( to see all the 10 items)

STL is very good at getting the job done quickly. But if there needs to be modification to existing design or if there is a bug then STL is more harder to debug and maintain vs MFC.
