+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+The Internals namespace is used by the core Perl development team to
+expose certain low level internals routines for testing and other purposes.
+.PP
+In theory these routines were not and are not intended to be used outside
+of the perl core, and are subject to change and removal at any time.
+.PP
+In practice people have come to depend on these over the years, despite
+being historically undocumented, so we will provide some level of
+forward compatibility for some time. Nevertheless you can assume that any
+routine documented here is experimental or deprecated and you should find
+alternatives to their use.
+.SS FUNCTIONS
+.IX Subsection "FUNCTIONS"
+.ie n .IP "SvREFCNT(THING [, $value])" 4
+.el .IP "SvREFCNT(THING [, \f(CW$value\fR])" 4
+.IX Item "SvREFCNT(THING [, $value])"
+Historically Perl has been a refcounted language. This means that each
+variable tracks how many things reference it, and when the variable is no
+longer referenced it will automatically free itself. In theory Perl code
+should not have to care about this, and in a future version Perl might
+change to some other strategy, although in practice this is unlikely.
+.Sp
+This function allows one to violate the abstraction of variables and get
+or set the refcount of a variable, and in generally is really only useful
+in code that is testing refcount behavior.
+.Sp
+*NOTE* You are strongly discouraged from using this function in non-test
+code and especially discouraged from using the set form of this function.
+The results of doing so may result in segmentation faults or other undefined
+behavior.
+.ie n .IP "SvREADONLY(THING, [, $value])" 4
+.el .IP "SvREADONLY(THING, [, \f(CW$value\fR])" 4
+.IX Item "SvREADONLY(THING, [, $value])"
+Set or get whether a variable is readonly or not. Exactly what the
+readonly flag means depend on the type of the variable affected and the
+version of perl used.
+.Sp
+You are strongly discouraged from using this function directly. It is used
+by various core modules, like \f(CW\*(C`Hash::Util\*(C'\fR, and the \f(CW\*(C`constant\*(C'\fR pragma
+to implement higher-level behavior which should be used instead.
+.Sp
+See the core implementation for the exact meaning of the readonly flag for
+each internal variable type.
+.IP hv_clear_placeholders(%hash) 4
+.IX Item "hv_clear_placeholders(%hash)"
+Clear any placeholders from a locked hash. Should not be used directly.
+You should use the wrapper functions provided by Hash::Util instead.
+As of 5.25 also available as \f(CW Hash::Util::_clear_placeholders(%hash) \fR
