    1. COSo, really, it's a deficiency in the language, not the compiler. Some compiler writers chose to break the standard in order to get around that deficiency (which is handy if that's the only compiler you use but otherwise hurts portability and causes problems), while others chose to follow the standard. Fortunately, the next standard fixes this deficiency in the language so that it will no longer be an issue. I really wouldn't say that it's a deficiency in the compilers though, since that's the way the current standard is.

    2. COGenerally speaking, any operation which alters a `vector` rather than an element in the `vector` could invalidate all iterators for that `vector`. So, it's generally a bad idea to alter a `vector` while iteratoring over it or needing to save any iterators to it. However, some operations - such as `erase()` - return a valid iterator to the next element, so it's possible to alter a `vector` in such situations and still have valid iterators, but you have to be careful with what you're doing or you can shoot yourself in the foot.

    3. CO@Konrad Most likely. But if you're compiler isn't inlining (and I don't think that gcc does short of -O3 - certainly that's when it starts using the -inline flag), then it won't inline. If you're compiler is doing inline optimizations, then yes it _will_ happen as long as length() is declared inline - which presumably it is. But if inlining isn't turned on in your compiler, then you're going to incur the cost.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
