.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module emulates the functionality of the accessors module, using
Class::MakeMethods to generate similar methods.
.PP
In particular, the following lines are equivalent:
.PP
.Vb 2
\&  use accessors \*(Aqfoo\*(Aq;
\&  use Class::MakeMethods::Template::Hash \*(Aqscalar \-\-get_set_chain\*(Aq => \*(Aqfoo\*(Aq;
\&
\&  use accessors::chained \*(Aqfoo\*(Aq;
\&  use Class::MakeMethods::Template::Hash \*(Aqscalar \-\-get_set_chain\*(Aq => \*(Aqfoo\*(Aq;
\&
\&  use accessors::classic \*(Aqfoo\*(Aq;
\&  use Class::MakeMethods::Template::Hash \*(Aqscalar\*(Aq => \*(Aqfoo\*(Aq;
.Ve
.PP
You may use this module directly, as shown in the \s-1SYNOPSIS\s0 above,
.PP
Furthermore, you may call \f(CW\*(C`use Class::MakeMethods::Emulator::accessors
\&\*(Aq\-take_namespace\*(Aq;\*(C'\fR to alias the accessors namespace to this package,
and subsequent calls to the original package will be transparently
handled by this emulator. To remove the emulation aliasing, call
\&\f(CW\*(C`use Class::MakeMethods::Emulator::accessors \*(Aq\-release_namespace\*(Aq\*(C'\fR. 
The same mechanism is also available for the classic and chained subclasses.
.PP
\&\fBCaution:\fR This affects \fBall\fR subsequent uses of the accessors module in
your program, including those in other modules, and might cause
unexpected effects.
