Named tokens

Provide a way to name a token, and bind these names by augmenting the data array to an object.

a -> name:string {% function(d) {return d.name;} %}

A breaking change, but I think a nicer solution to this would be to use apply() instead of call() for preprocessors. So you get arguments, rather than a single array argument.

Then you can write (in ES6 at least):

a -> [\w]:+ _ [0-9]:*   {% (id, _, count) => ({ id, count }) %}

That’s still kinda possible by destructuring the parameter:

a -> [\w]:+ _ [0-9]:*   {% ([ id, _, count ]) => ({ id, count }) %}
