+=head1 DESCRIPTION
+
+=begin original
+
+One thing Perl porters should note is that F<perl> doesn't tend to use that
+much of the C standard library internally; you'll see very little use of,
+for example, the F<ctype.h> functions in there. This is because Perl
+tends to reimplement or abstract standard library functions, so that we
+know exactly how they're going to operate.

+C<FILE*> types may not even be available. See also the C<perlapio>

+Sometimes instead of zeroing the allocated heap by using Newxz() you
+should consider "poisoning" the data. This means writing a bit
+pattern into it that should be illegal as pointers (and floating point
+numbers), and also hopefully surprising enough as integers, so that
+any code attempting to use the data without forethought will break
+sooner rather than later. Poisoning can be done using the Poison()
+macros, which have similar arguments to Zero():

+There are several types of character class tests that Perl implements.
+The only ones described here are those that directly correspond to C
+library functions that operate on 8-bit characters, but there are
+equivalents that operate on wide characters, and UTF-8 encoded strings.
+All are more fully described in L<perlapi/Character classification> and
+L<perlapi/Character case changing>.

+The C library routines listed in the table below return values based on
+the current locale. Use the entries in the final column for that
+functionality. The other two columns always assume a POSIX (or C)
+locale. The entries in the ASCII column are only meaningful for ASCII
+inputs, returning FALSE for anything else. Use these only when you
+B<know> that is what you want. The entries in the Latin1 column assume
+that the non-ASCII 8-bit characters are as Unicode defines, them, the
