Negating values broken in 2.X

[alexlafroscia]

The following CSS transform used to work in 1.X

/* source */
foo {
  left: calc(-(100px - 10px));
}

/* expected */
foo {
  left: -90px;
}

However, as of 2.X, this just throws an error.

If you past the source example above into http://cssnext.io/playground/, you can see that nothing is produced (which I take to mean it couldn't compile).

Try multiplying with -1 instead.

Sure, that works and is what I did. But what used to work should continue to work, too.

Yep. But looks like nobody has the time to find and patch the root cause.

Can you take a look at #31 guys?

It never worked in browsers. The fact that it used to work in the plugin was the result of a bug.

@alexlafroscia

foo {
  left: calc(-(100px - 10px));
}

This is incorrect calc expression. Looks like this breaking in major version update is ok.
