If you write the following code, when you click on the code after FOR_ALL macro in function _tmain, the parser shows FOR_ALL as active function and all activities regarding selecting functions and scopes are disrupted.

#define FOR_ALL( VEC , pVAR ) for ( decltype( ( VEC ).begin() ) pVAR = ( VEC ).begin() ; pVAR != ( VEC ).end() ; pVAR++ )

int _tmain(int argc, _TCHAR* argv[])
{
vector<long> theList ;

FOR_ALL( theList , pItem )
{ cout << * pItem << "\n" ;}

return 0;
}

Visual Studio 2012

Just write the code above and it happens.

When you use a macro like what I wrote above, the function scopes are disrupted and the macro is shown as function name.

Macros won't affect function names.

If I add an extra parameter to the function and use a constant number as that parameter, the problem is resolved:

e.g.:
#define FOR_ALL( VEC , pVAR , TEMP ) for ( decltype( ( VEC ).begin() ) pVAR = ( VEC ).begin() ; pVAR != ( VEC ).end() ; pVAR++ )

and use FOR_ALL( theList , pItem , 0 )

also, if I don't have "for" in macro definition, the problem does not happen:

#define FOR_ALL( VEC , pVAR ) ( decltype( ( VEC ).begin() ) pVAR = ( VEC ).begin() ; pVAR != ( VEC ).end() ; pVAR++ )

and use for FOR_ALL( theList , pItem )
