Added args-parse

[TrySound]

Hi, @coderhaoxin !
What do you think about ast?

I use similar in postcss-value-parser

[TrySound]

I can concat everything between commas if there are more than one entities. You think it's a good way?

[TrySound]

//= if ("str" === dsf) => [{ type: 'expr', value: '"str" === dsf' }]

//= include('name', {}) => [{ type: 'string', value: 'name', { type: 'obj', value: '{}' } }]

LGTM

If there are more normal use cases, maybe you can split it to another separate module.

@coderhaoxin I want to make full parser soon. For now this thing is just but fix.
