Today we ship a one-type-fits-all style for printing type is not assignable to type messages. We'd like to improve this in a pretty simple manner: by occasionally adding newlines. For example with this arbitrary comparison:

let a = { b: { c: { e: { f: 123 } } } };
let b = { b: { c: { e: { f: "123" } } } };
a = b;

Looks like this today:

Hello,

I recently upgraded to Node v4.17.5 and it seems a newly added exception there is breaking my Less build.

I'm using less v4.1.1 and less-plugin-autoprefix v2.0.0. To recreate the issue I've -

1. Installed the above packages globally
2. Created a less file (test.less) with the following content -

p {
    color: blue;
}

3. On the command line, run -
   `lessc test.less tes

Abstract

The AST import code in CommandLineInterface is currently wrapped in an exception handler that catches all exceptions and prints an error message. This is most likely because the JSON input does not get validated before it's passed to ASTJsonImporter and the importer just asserts things that

### Example
let unreachableProxy = "http://127.0.0.1:8888"
try:
  let client = newHttpClient(proxy=newProxy(unreachableProxy), timeout=1)
  var res = client.getContent("https://github.com")
  echo res
except:
  echo "Timed out"

Current Output

timeout variable is ignored, program stuck until default socket timeout will happen

Expected Output

Timed out a

Specifically two related issues:

• Nan's should be lowercased (similar to #3034)
• Signs for nan should be included (always +), an issue really if the real part of the complex number is != 0.

For example, in Python:

>>> complex(0, float('nan'))
nanj
>>> complex(float('nan'), float('nan'))
(nan+nanj)
>>> complex(float('nan'), -float('nan'))
(nan+nanj)
>>> complex(-flo

It would be useful to have a java.util.BitSet implementation. It looks like most Java collections are available but this one fell through the cracks (perhaps because it's not part of the Collection hierarchy).
