Get the C<length> of a capture variable. There's a special callback
for this so that perl doesn't have to do a FETCH and run C<length> on
the result, since the length is (in perl's case) known from an offset
-stored in C<<rx->offs> this is much more efficient:
+stored in C<< rx->offs >> this is much more efficient:
I32 s1 = rx->offs[paren].start;
I32 s2 = rx->offs[paren].end;

-In the 5.9.x development version of perl you can C<<use re Debug => 'PARSE'>>
+In the 5.9.x development version of perl you can C<< use re Debug => 'PARSE' >>
to see some trace information about the parse process. We will start with some
simple patterns and build up to more complex patterns.
=item MY_CXT_CLONE
By default, when a new interpreter is created as a copy of an existing one
-(eg via C<<threads->create()>>), both interpreters share the same physical
+(eg via C<< threads->create() >>), both interpreters share the same physical
my_cxt_t structure. Calling C<MY_CXT_CLONE> (typically via the package's
C<CLONE()> function), causes a byte-for-byte copy of the structure to be
taken, and any future dMY_CXT will cause the copy to be accessed instead.
