/*
* The first field of every node is NodeTag. Each node created (with makeNode)
* will have one of the following tags as the value of its first field.
*
* Note that the numbers of the node tags are not contiguous. We left holes
* here so that we can add more tags without changing the existing enum's.
* (Since node tag numbers never exist outside backend memory, there's no
* real harm in renumbering, it just costs a full rebuild ...)

Yes, it’s unusual in that the main female character is so unapologetically obsessed with her own lust and sexuality – in fact it’s the driving plot point throughout. But the thing that made it particularly tricky reading was the fact that Celeste is clearly a paedophile. There’s no middle ground (insomuch as you might think it’s possible to have one), there’s no moral hand wringing on her part, and she isn’t pursued by a particularly mature 16-year-old for whom she feels a very real connection. -- Barry? 2015-05-07 (木) 06:28:37
