Work has begun on implementing the Cobra compiler in Cobra. The improvements
below reflect discoveries during this task.

In this release:

== Additions ==

* Added new --superstacktrace option to compiler. Now uncaught exceptions
  include:

    * argument names and values
    * local variable names and values
    * line numbers

  When not using the --test option, this requires a little manual coding at
  the top level of your program; four extra lines:

    def main is shared
        try
            ...
        catch
            CobraCore.dumpStack()
            throw

  --sst can be used as an abbreviation for --superstacktrace

* Added raw string literals which do not interpret backslashes or square
  brackets. These are primarily for regular expressions and Windows-style file
  paths.

    re = Regex(r'[\n\t ]+')

    using file = File.openText(r'C:\Shared\Samples\Sample1.text')
        ...


== Changes and Minor Improvements ==

* Extended "in" and "not in" operators to handle characters and strings
  such as `if someChar in someString`.

* Altered the "one liner" syntax for require and ensure so that a `code`
  section is not required or even expected. That was the original intention:

    def totalItems(items as List<of Item>)
        require items
        sum = 0.0
        for item in items
            sum += item.amount
        return sum


== Fixes ==

* Fixed a bug in `require` and `ensure` which didn't allow for truthfulness in
  the same way that `assert`, `if` and `while` do.

* Fixed a bug where `print x` caused an exception when x was nil.

* Fixed a bug where the type of `t[i]` could not be inferred if t's type was
  nilable (such as `List<of String>?`).
