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

Looking at the list of Yul transformations in the documentation, I noticed a few slight differences between the list at https://docs.soliditylang.org/en/latest/yul.html#optimization-step-sequence and the list at https://docs.soliditylang.org/en/latest/internals/optimizer.html#optimizer-steps:

• In the second list, change FunctionalInliner to ExpressionInliner, just like in the first list.

### 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

In CPython:

>>> from collections import deque
>>> class MyDeque(deque): pass
>>> MyDeque()
'MyDeque([])'

While in RustPython:

>>>>> from collections import deque
>>>>> class MyDeque(deque): pass
>>>>> MyDeque()
deque([])

This needs to be applied for set, frozenset and bytearray too.

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).
