+=head1 LIMITATIONS of B<-x>
+
+F<h2xs> would not distinguish whether an argument to a C function
+which is of the form, say, C<int *>, is an input, output, or
+input/output parameter. In particular, argument declarations of the
+form
+
+ int
+ foo(n)
+ int *n
+
+should be better rewritten as
+
+ int
+ foo(n)
+ int &n
+
+if C<n> is an input parameter.
+
+Additionally, F<h2xs> has no facilities to intuit that a function
+
+ int
+ foo(addr,l)
+ char *addr
+ int l
+
+takes a pair of address and length of data at this address, so it is better
+to rewrite this function as
+
+ int
+ foo(sv)
+ SV *addr
+ PREINIT:
+ STRLEN len;
+ char *s;
+ CODE:
+ s = SvPV(sv,len);
+ RETVAL = foo(s, len);
+ OUTPUT:
+ RETVAL
+
+or alternately
+
+ static int
+ my_foo(SV *sv)
+ {
+ STRLEN len;
+ char *s = SvPV(sv,len);
+
+ return foo(s, len);
