+## 1. `$$` is PID of interpreter
+
+`$$/$$ = 1`
+
+## 2. magic variables
+
+`$.` and `$_` can be reassigned.
+
+`@_` is a plain instance variable of `main`.
+
+## 3. lambda syntax
+
+```ruby
+l1 = lambda {|args| body}
+l2 = ->(args){body}
+
+l1.call(args)
+l1.(args)
+l2[args]
+
+l1<<l2 #=> ->(args){l1[l2[args]]}
+```
+
+## 4. %-literals for string:
+
+* `[` and `]`
+* `(` and `)`
+* `{` and `}`
+* `<` and `>`
+* **Any other character, as both beginning and ending delimiters.**
+
+`%%% = ''`
+
+## 5. `String#<<`
+
+Append the string with value provided, then return the modified string (self).
+
+`String#<<(Integer)` implies `Integer#chr`.
+
+## 6. `$>`
+
+Defaults to `$STDOUT`.
+
+`io << value` prints `value` to `io` then return `io`.
+
+## 7. Misc
+
+Character `'l'`, `'o'`, `'r'` are kept according to the requirements.
