[hyperion] 14338: New syntax for PSEH. UNTESTED, any takers? It can be used like this:

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