When inside single quotes, Perl tokenizes \ as an error

[miparnisari]

Problem:

I tried adding the following rule as the 3rd rule of states :sq and :dq and it fixes it, but of course IDK if this is the right solution.

      state :sq do
        rule /\\[']/, Str::Escape
        rule /[^\\']+/, Str::Single
+        rule /\\/, Str::Single
        rule /'/, Punctuation, :pop!
      end

      state :dq do
        mixin :string_intp
        rule /\\[\\tnr"]/, Str::Escape
        rule /[^\\"]+?/, Str::Double
+        rule /\\/, Str::Single
        rule /"/, Punctuation, :pop!
      end

B'oh—well that's a silly mistake.

I think the fix for :sq is right but I'm less sure about :dq. When I try a very rudimentary print statement at the command line with Perl then passing a double-quoted string with a single backslash omits from the output the character that was escaped.

So we probably want to highlight both the backslash and the immediately following character with the Str::Escape token.
