babel-preset-vue's Issues

Adding sugar

I think we could add sugar transforms to this preset as a complex preset. Here's draft release notes. It's 100% reverse compatible. The only thing that could be potentially affected is:

const A = () => <h1>Hello</h1>

But since we use this.$createElement this syntax is not likely to be used anywhere.

@yyx990803, @egoist, what do you think?

prevent auto convert HTML escape characters

For Example:
in parent:
render(){ return ( <div>abc &lt; </div> ) }

in child
this.$slots.default // we have "abc <"

Is there any way to prevent auto-converting &lt; to < ?

Syntax error on valid code.

> mocha --require babel-register --require test/unit/setup.js "test/**/*.spec.js"

For some reason it doesn't believe I can have a '.' in an argument?
