postcss-tape : type checker

Not sure about this one yet, but it seemed useful.

It's relatively easy to mess up a single prop assignment that isn't immediately visible to us in our own tests.

rule.selector = ['.foo', '.bar'];

That would still serialize fine because an array of strings happens to concat with , by default in JavaScript.

But another plugin doing selector.replace(...) would get an on such a node.

Going to close for now, we already have TypeScript to guard against the same underlying issue.
