operator names change in 0.2

[Stepan Koltsov]

Hi, all.

Since 0.1 operator names changed in Clay: "+=" is now "+:" and "&" is "@". This is a bit unusual for people who came from C/C++ world. What is the motivation behind these changes?

0.2 added Haskell-style user-defined operators, and `&` and `=` are
now available as operator characters. The motivation of renaming the
update and address syntax, which are primitive syntax, was to free up
those characters unambiguously. `@` is used as the address operator in
Pascal so fits somewhat with postfix `^` for dereference. `op:` isn't
great but seemed like the least bad option at the time.

I see, += can be overloaded:

```
(+=)(a, b) { a +: b; }
```

Shouldn't be this and similar functions added to standard library?

I don't see a need for both syntaxes. That would just be misleading.
