Currently only the transpiler is tested, but I have to test the runtime aswell. Especially since there are many finicky cases:
1) Transformers.js is creating callable class instances and they are considers "typeof value === 'function'" but also value instanceof Object... no big surprise here.
2) typeof Object.create(null) ==='object' but not Object.create(null) instanceof Object
So neither can we use onlytypeof nor instanceof... and these kinds of cases require tests, since it's beyond obvious, but also easier functions should have a bunch of tests each.
