New syntax for PSEH. UNTESTED, any takers? It can be used like this:

Browse source 
_SEH2_TRY
{
 // Code that might raise an exception
}
_SEH2_EXCEPT(FilterFunc)
{
 // Handle the exception
}
_SEH2_END;

or like this:

_SEH2_TRY
{
 // Code that might raise an exception
}
_SEH2_FINALLY(UnwindFunc)
_SEH2_END;

or even like this (but PLEASE forget I said it):

_SEH2_TRY
{
 // Code that might raise an exception
}
_SEH2_EXCEPT(FilterFunc)
{
 // Handle the exception
}
_SEH2_FINALLY(UnwindFunc)
_SEH2_END;

_SEH2_TRY
{
 // Code that might raise an exception
}
_SEH2_END;
