1.0.0-alpha.11

• Reworked parsing to produce AST, other parts reworked to consume AST as well
• Exposed syntax interface with 3 methods: parse(source, tolerantMode), compile(ast, suggestRanges, statMode) and stringify(ast)
• Added slice notation like proposed for adding to JavaScript, e.g. $str: '<foo>'; str[1:-1] ('foo') or $ar:[1,2,3,4,5,6]; $ar[-3::-1] ([6,5,4]) (#11)
• Added slice(from, to) method
• Added split(pattern) method
• Added join(separator) method
• Added match(pattern, matchAll) method
• Fixed method invocation on recursive mapping, i.e. ..method() doesn't raise an error now and works as expected without surrounding parentheses (#10)
• Allowed definitions to use in parentheses, e.g. ($a: 1; $a + $a)
• Added a function definition via =>, i.e. => body
• Added sorting function definition with asc and desc keywords, e.g. sort(foo asc), $sorting: foo desc; sort($sorting) or sort(foo desc, bar asc)
• Changed sort() method to use a two argument function as a regular comparator
• Removed ::self syntax, recursion with a function defined by a variable should be used instead
