+python3 hystricomorph.py -c -i -l match
+"ABC" : 1
+"ABCD" : 2
+```
+
+This will generate a function (`int match(const char *)`) which is essentially:
+
+```
+int match(const char *cp) {
+	if (!strncasecmp(cp, "abcd\x00", 5)) return (2 << 8) | 4;
+	if (!strncasecmp(cp, "abc\x00", 4)) return (1 << 8) | 3;
+	return 0;
+}
+```
+
+But hopefully more efficient...
