36306	Allow simple_tag to parse @/:/- attributes	Giannis Terzopoulos	Giannis Terzopoulos	"I'm following up on the forum discussion: https://forum.djangoproject.com/t/proposal-allow-simple-tag-to-parse-attributes/36769

I think a sensible first step is trying an opt-in argument as Adam suggested, e.g., `allow_all_attrs=True` or perhaps `allow_all_html_attrs=True`. 

For implementation details, I propose:
1. Whitelisting common punctuation characters (`@`, `:`, `-`) for attribute names
2. Making these attributes accessible directly (only) from kwargs, such as `kwargs[""@hello""]`"	New feature	closed	Template system	dev	Normal	wontfix		Carlton Gibson Adam Johnson	Unreviewed	0	0	0	0	0	0
