__END__

=encoding utf-8

=head1 Normalization

Check that the string compiles.

=head2 Rationale

Why would we not want to catch syntax errors?

=head1 possible violations

=over 4

=item Bracket Notation Error

There was a problem compiling the string. 

The string is replaced with a comment that details the problem, typically including an escaped verison of the problematic string: [comment,Bracket Notation Error: DETAILS_GO_HERE]

=back 

=head1 possible warnings

None
