With the release of PPR v0.001000 there is a backwards incompatible
change in the definition of the `PerlTerm` rule to include postfix
arrows for dereferencing and methods.
This affects the plugin(s):
$ git grep -lP '\b(Perl)?(Term|((ScalarAccess|ArrayAccess)(NoSpace)?))' lib/
lib/Babble/Plugin/PostfixDeref.pm
Newer PPR handles the postfix dereference in `PerlTerm` while `PerlScalarAccess` handles indexing without any arrows. This also addresses the issue of <shadow-dot-cat#3>. This adds the tests from that PR (djerius++). Co-authored-by: Diab Jerius <djerius@cfa.harvard.edu>
For PostfixDeref that is interpolated in quote-likes.
Using `map` to translate the postfix subscripts does not work with
`push`, `pop`, `shift`, `unshift`, `splice`, and other built-ins that
modify the parameter as the `map` is using a copy.
This change makes the translation of
```perl
$foo->$*
```
into
```perl
${ $foo }
```
instead of
```perl
(map $$_, $foo)[0]
```
Fixes <shadow-dot-cat#13>.
