Is it legal and possible to access the return value in a finally block?

Dim RetVal as RetType

try
...
if ... then
    RetVal = RetType.FailedParse
    end try
endif
...

finally
    select case RetVal
        case ...
            UserStr = ...
    end select
end try

return RetVal

SomeType result = default(SomeType); // for "definite assignment"
try {
   // ...
   return result;
}
finally {
    // inspect "result"
}

Public Function MyFunc() as integer
    Try
      if DoSomething() = FAIL Then
        return FAIL
      end if

  Finally
      if MyFunc = FAIL then
          Me.ErrorMsg = "failed"
      endif
  End Try
End Function

if MyFunc = FAIL Then

if MyFunc() = FAIL Then
