ProhibitMatchVars doesn't detect match vars inside interpolated strings

[h3xx]

The following usages are not detected but should be. The minute you take them out of the strings, they're detected, however.

"$`";
"$&";
"$'";
"$PREMATCH";
"$MATCH";
"$POSTMATCH";

Example:

$foo = 'foo' . $`; # detected
$foo = "foo$`"     # NOT detected
qr/$`/;            # NOT detected
<<"HEREDOC";       # NOT detected
$`
HEREDOC

I suspect this is a PPI issue over a Perl::Critic issue, but I haven't looked.

Not sure if that's correct; P:V:ProhibitPunctuationVars has routines in it to detect its illegal variables being used in heredocs and regexes.

I would imagine the fix would be implementing something similar in P:V:ProhibitMatchVars.
