Possible to Customize Haml Expansion?

First and foremost, thanks for an AMAZING utility! I'm looking forward to putting it to use.

I was playing with Emmet for expanding HAML this morning and came across one thing that, after researching, I can't figure out how to customize and I was hoping someone might be able to point me in the right direction.

If I type the following in a HAML file

html:5

and expand it, I get the following

!!! 5
%html{:lang => "en"}
  %head
    %meta{:charset => "UTF-8"}
    %title
  %body

It's beautiful! I'm curious, however, to know if there's a way to customize the haml output to utilize the parenthesis syntax as opposed to the hash syntax? I would love to see the below instead

!!! 5
%html(lang="en")
  %head
    %meta(charset="UTF-8")
    %title
  %body

Is there a configuration somewhere you can point me to?

Thanks in advance!

The issue names no files, tests, or entry points. Start by reviewing the existing Haml expansion configuration and the four-comment discussion; done means determining whether the requested parenthesis syntax can be configured and documenting or implementing that behavior if it is supported.
