autobox::dump \- human/perl readable strings from the results of an EXPR
.SH "VERSION"

.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
The autobox::dump pragma adds, via the autobox pragma, a method to 
normal expression (such as scalars, arrays, hashes, math, literals, etc.)
that produces a human/perl readable representation of the value of that
expression.

Has all the issues autobox has.
.PP
Has all the issues Data::Dumper has.
.PP
This pragma errs on the side of human readable to the detriment of
Perl readable.  In particular it uses the terse and deparse options
of Data::Dumper by default.  These options may create code that cannot 
be eval'ed.  For best eval results, set options to \f(CW\*(C`qw/Purity/\*(C'\fR.
Note, this turns off coderef dumping.
