+ *
+ * If just one bit is required, it seems to me (khw) that the best option would
+ * be to turn the ANYOF_LOC_REQ_UTF8 bit into a separate node type: a
+ * specialization of the ANYOFL type, freeing up the currently occupied bit.
+ * When turning a bit into a node type, one has to take into consideration that
+ * a SSC may use that bit -- not just a regular ANYOF[DL]?. In the case of
+ * ANYOF_LOC_REQ_UTF8, the only likely problem is accurately settting the SSC
+ * node-type to the new one, which would likely involve S_ssc_or and S_ssc_and,
+ * and not how the SSC currently gets set to ANYOFL. This bit is a natural
+ * candidate for being a separate node type because it is a specialization of
+ * the current ANYOFL, and because no other ANYOFL-only bits are set when it
+ * is; also most of its uses are actually outside the reginclass() function, so
+ * this could be done with no performance penalty. The other potential bits
+ * seem to me to have a potential issue with a combinatorial explosion of node
+ * types, because of not having that mutual exclusivity, where you may end up
+ * having to have a node type for bitX being set, one for bitY, and one for
+ * both bitXY.
+ *
+ * If you don't want to do this, or two bits are required, one could instead
+ * rename the ANYOF_POSIXL bit to be ANYOFL_LARGE, to mean that the ANYOF node
+ * has an extra 32 bits beyond what a regular one does. That's what it
+ * effectively means now, with the extra space all for the POSIX class bits.
+ * But those classes actually only occupy 30 bits, so the ANYOF_LOC_REQ_BIT (if
+ * an extra node type for it hasn't been created) and/or the ANYOF_LOC_FOLD
+ * bits could be moved there. The downside of this is that ANYOFL nodes with
+ * whichever of the bits get moved would have to have the extra space always
+ * allocated.
+ *
+ * If three bits are required, one could additionally make a node type for
+ * ANYOFL_LARGE, removing that as a bit, and move both the above bits to that
+ * extra word. There isn't an SSC problem as all SSCs are this large anyway,
+ * and the SSC could be set to this node type. REGINCLASS would have to be
+ * modified so that if the node type were this, it would call reginclass().
+ * as the flag bit that does this now would be gone.
