Go语言中常见的陷阱是什么？ [关闭]

I am planning to do some program analysis on Golang, just like pylint, trying to find issues from source code. So the first question I need to ask is:

What are the common pitfalls specialized in the Go language?

I know there are some ones in Python, e.g. array variables '[]' as parameters, and mutable vs immutable objects. (See more here and there).

Example 1:

>>> def spam(eggs=[]):
...     eggs.append("spam")
...     return eggs
...
>>> spam()
['spam']
>>> spam()
['spam', 'spam']
>>> spam()
['spam', 'spam', 'spam']
>>> spam()
['spam', 'spam', 'spam', 'spam']

Example 2:

Map<Person, String> map = ...
Person p = new Person();
map.put(p, "Hey, there!");

p.setName("Daniel");
map.get(p);       // => null

So what I really want to know is the similar ones in Golang. I have search the web but cannot find it. I also review some git repository history (e.g. docker.io) but cannot get typical ones. Could you kindly provide me some examples such as memory leaks, concurrency, unexpected results, and misunderstandings.

Golint is a linter for Go source code.
