  * This is a grab bag of functions for string operations, designed to enhance
  * the standard string.h.
  *
+ * Note that if you define CCAN_STR_DEBUG, you will get extra compile
+ * checks on common misuses of the following functions (they will now
+ * be out-of-line, so there is a runtime penalty!).
+ *
+ *     strstr, strchr, strrchr:
+ *             Return const char * if first argument is const (gcc only).
+ *
+ *     isalnum, isalpha, isascii, isblank, iscntrl, isdigit, isgraph,
+ *         islower, isprint, ispunct, isspace, isupper, isxdigit:
+ *             Static and runtime check that input is EOF or an *unsigned*
+ *             char, as per C standard (really!).
+ *
  * Example:
  *     #include <stdio.h>
  *     #include <ccan/str/str.h>
