The some kinds of expression with unboxing operation, e.g. x + y... or x... + y, cannot be compiled.

Let VM support hook function.

The instruction 'unbox' will throw an error when value is not a tuple, which is not expected for pattern matching.

In old version, user should write [ 'foo': 1, 'bar': 2 ], which seems inconvenient, and use variable as key in table literal is rarely.
So, the literal like [ foo: 1, bar: 2 ] will be used to instead [ 'foo': 1, 'bar': 2 ].

Matching pattern can not group pattern in right way.

The program alo crash occasionally when typed in a = [1: 2, 2: 3, 3: 4], which is a valid assignment statement.

The features in 0.1.

• basic rich-operand instruction set.
• basic C-interaction API.
• basic meta function support.
• basic unary and binary operation support.
• compelling, serializing and deserializing function.
• class library, includes supporting of inheritance.
• string library, includes support of regular expression.
• math library, includes basic math function.
• list and table library, include basic operation for list and table.
• IO library, includes stream support.
• system library, includes some OS specialized controlling functions.

Some of expression may fail to match the string which should be match. For example, code
println('(ab?)b'->match 'ab') will show false, but it should show true.

• fix bug mentioned.
• add possible test examples.

Before 'new' in Alopecurus is just a syntactic sugar that like following code: new Type(p1, p2) is equivalent to Type.__new([:], p1, p2). However, this way ignored that some of type is not inherit from 'table' type and the meta table of new object is not its type.
Here is the TODO list of following version:

• let 'new' become a instruction in the code list.
• add code generation supporting.

Now I added automatic configuration to identify compiling environment. It should support Linux and MacOS, however I cannot test the compiled result in these OS. They should be tested in the future.

Moreover, should the program should support more OS?
