Language extension for html5 data attributes

[Priit]

Hi!

I'm using haml since 2007 and love it, great work!

Currently we are doing html5 jqurey mobile development and would like to simplify data syntax for haml.

Current syntax:
%div{:data => {:role => 'header', :theme => 'b'}}

I suggest:
.d-role-header.d-theme-b

Where 'd-' will indicate it's actually data attribute, second part will  be the hash key (example: role, theme etc) and last parts will be values (examlpe: header, b etc).

I made quick demo implementation: https://github.com/priit/haml/commit/9551419dba759c587380ec221504ae2745baf57f

We are using it with two projects and my coworkers love it so far.

I would love to go further, should haml community accept this custom data behavior into haml language (that would be great!) or should I go with separate extension as gem direction instead?

What do you think about it?

Thanks for any feedback!

Cheers,
Priit

I like the idea to shortcur the data attributes, but I think "d-" syntax is a little bit confusing it would be great to have something more explicit. Maybe involve a special character, or something.
