There is no clear rule to distinguish between code-block and hash-ref!!!
The parser uses DWIM heuristics to guess if it looks more like a hash-ref or not. (Furthermore "w/o look-ahead")
So in complicated cases you need to give hints for what you mean.
This ambiguity should be one reason why Perl6 switched from {} to <> to indicate hashes.

well it's a perfect hash-ref!
DB<112> $hr={ "$_"."=s" => \$opt{$_} } => { "=s" => \undef }
But I think the used heuristic must be quite simple, something like
(bareword || variable) (comma || fatcomma) (expr)
So "$_"."=s" is already to complex to fit this rule of thumb.
