 The PEG syntax is well described on page 2 in the [document](http://www.brynosaurus.com/pub/lang/peg.pdf) by Bryan Ford. *cpp-peglib* also supports the following additional syntax for now:
 
-  * `'...'i` (Case-insensitive literal operator)
-  * `[...]i` (Case-insensitive character class operator)
-  * `[^...]` (Negated character class operator)
-  * `[^...]i` (Case-insensitive negated character class operator)
-  * `{2,5}` (Regex-like repetition operator)
-  * `<` ... `>` (Token boundary operator)
-  * `~` (Ignore operator)
-  * `\x20` (Hex number char)
-  * `\u10FFFF` (Unicode char)
-  * `%whitespace` (Automatic whitespace skipping)
-  * `%word` (Word expression)
-  * `$name(` ... `)` (Capture scope operator)
-  * `$name<` ... `>` (Named capture operator)
-  * `$name` (Backreference operator)
-  * `|` (Dictionary operator)
-  * `↑` (Cut operator)
-  * `MACRO_NAME(` ... `)` (Parameterized rule or Macro)
-  * `{ precedence L - + L / * }` (Parsing infix expression)
-  * `%recovery(` ... `)` (Error recovery operator)
-  * `exp⇑label` or `exp^label` (Syntax sugar for `(exp / %recover(label))`)
