* probably better than that commit anyway. But it could be reinstated if we

+ * probably the POSIXL one. Now that there is an ANYOFL (locale) node, another
+ * option would be to make all of those include the POSIXL data structure,
+ * which would get rid of needing a separate POSIXL flag. But it would
+ * increase the size of all such nodes, so it's probably not as atractive as
+ * having an ANYOF_POSIXL node type. But if we did do it, note that not all 32
+ * bits of that extra space are used, one bit of that could be set aside for
+ * the LOC_FOLD flag, yielding yet another bit. This would require extra code
+ * for masking, so again not the most attractive solution.

* Several flags are not used in synthetic start class (SSC) nodes, so could be
* shared should new flags be needed for SSCs, like SSC_MATCHES_EMPTY_STRING
* now. */
