variable or closure. You tried to hoist something "bigger" than that.


=item C<< failed => "because there is no variable at the specified location" >>

You called C<classify_var_at()> but gave it a position in the source code
where there was no variable. If you're doing that from within some editor,
you may have an out-by-one error if the buffer positions you're detecting
and passing back to the module start at 1 instead of zero.


=item C<< failed => 'because the apparent variable is not actually a variable' >>

You called C<classify_var_at()> but gave it a position in the source code
where there was no variable. It I<looks> like there is a variable there,
but there isn't. Is the apparent variable actually in an uninterpolated
string, or a comment, or some POD, or after the C<__DATA__> or C<__END__>
marker?

=back

API errors are signalled by throwing an exception:

=over

=item C<< "%s argument of %s must be a %s" >>

You called the specified subroutine with the wrong kind of argument.
The error message will specify which argument and what kind of value it requires.

=item C<< "Unexpected extra argument passed to %s" >>

You called the specified subroutine with an extra unexpected argument.
Did you mean to put that argument in the subroutine's options hash instead?

=item C<< "Unknown option (%s) passed to %s" >>

You passed an unexpected named argument via the specified subroutine's
options hash. Did you misspell it, perhaps?

=head1 CONFIGURATION AND ENVIRONMENT

Code::ART requires no configuration files or environment variables.


=head1 DEPENDENCIES

The PPR module (version 0.000027 or later)


=head1 INCOMPATIBILITIES

Because this module relies on the PPR module,
it will not run under Perl 5.20
(because regexes are broken in that version of Perl).


=head1 BUGS AND LIMITATIONS

These refactoring and analysis algorithms are not intelligent or
self-aware. They do not understand the code they are processing, and
especially not the purpose or intent of that code. They are merely
applying a set of heuristics (i.e. informed guessing) to try to
determine what you actually wanted the replacement code to do. Sometimes
they will guess wrong. Treat them as handy-but-dumb tools, not as
magical A.I. superfriends. Trust...but verify.

No bugs have been reported.
