Additional method of defining boolean HTML attributes

[stephendolan]

Lucky's current attrs helper takes in an Array(Symbol).

This is super convenient for stuff like always setting a button to disabled on page load, but is trickier with dynamic attributes based on page data.

What are the group's thoughts on another implementation that can take in a Hash(Symbol, Boolean)?

For example, it would allow me to turn this:

option version, attrs: [version == selected_version ? :selected : nil].compact

Into this:

option version, attrs: { selected: selected_version? }

This isn't an original idea, and basically came from me trying to write attributes out the same way that Vue does.

To avoid breaking changes, I could totally see a world where I have both signatures available, and without diving into the code I couldn't say for sure, but maybe we could even simply call the Array(Symbol) implementation from the Hash(Symbol, Boolean version.
