Ruby syntax has various ambiguous and context-dependent elements

- regex (/patt/), percent literal (%_abc_) and heredoc (<<x) begin with operators.
    puts %q+1+
         ~ percent literal
    puts a %q+1+
           ~ operator
  Note that regexes and oercent literal are indecisive because they depend on whether
  the element on the left is a function or a variable. Therefore we assume a regex.
    foo /a # (without space after /) operator or regex ?
- 'do' creates a block (begin/endRegion), but is optional with 'for', 'until' and 'while'.
    for x in a
      puts x
    end

    for x in a do
      puts x
    end
- 'if', 'unless', 'until' and 'while' when preceded by a value are modifiers
  without closure (not a block region).
    a += 1 while a < 10
- '?' which is a function suffix, a literal char or a ternary operator
    foo??a?1: 2
    ~~~~ func
        ~~ char
          ~ ~ ternary operator

For consistent highlighting and regions, the syntax is split into 3 parts:
- function call (first element of an expression)
- operator
- value

Each token fits into one of its categories and is followed by 1 or more of its
categories. For example, 'and' is an operator followed by a function call,
operator or value in order of priority.
So '/' in 'and /' corresponds to a regex.

Notes:
- 'do' is a value that creates a block, except in the condition of 'for', 'until' and 'while'.
- 'if', 'unless', 'until' and 'while' are modifiers only in the value category.

<!--
		NOTE This syntax should be synchronized with Haml, for which a ',' and ' |' at
		the end of a line correspond to a <LineContinue>.
