My understanding of the semantic of the return statement is that the
expression following return is evalated, a copy of the value is
created using the appropriate copy constructor and the copy is
returned. My question involves the circumstance
extern MyObj foo();
...
foo();
What becomes of the return value? Borland C++ waits until it reaches
the end of the scope enclosing the call to foo() before calling the
destructor for its return value. If a destructor is to be called then
when. In a case such as
extern MyObj foo();
...
loop:
foo();
...
goto loop;
will a destructor be called for every value returned by foo()?
