Hyphen/dash attributes instead of underscore in Haml -

doing this

li{ id: ["article", article.id] }

results in

# => <li id="article_1"></li>

i want have output instead, while using similar dynamic syntax, rather string parsing.

# => <li id="article-1"></li>

without doing

%li{ id: "entry-#{entry.id}" }

it seems cannot this. hope haml realizes people don't underscores element names, , naysayers object implementing on grounds of complexity realize they're arguing status quo.

in meanwhile, can this, more manual.

li{ id: "article-#(article.id)" }
