 * [ChaiScript](http://chaiscript.com/) - A strong inspiration for Rhai.  An embedded scripting language for C++ that I helped created many moons ago, now being lead by my cousin.
 * You can also check out the list of [scripting languages for Rust](https://github.com/rust-unofficial/awesome-rust#scripting) on [awesome-rust](https://github.com/rust-unofficial/awesome-rust)
 
 ## Examples
+
 The repository contains several examples in the `examples` folder:
-- `arrays_and_structs` demonstrates registering a new type to Rhai and the usage of arrays on it
-- `custom_types_and_methods` shows how to register a type and methods for it
-- `hello` simple example that evaluates an expression and prints the result
-- `reuse_scope` evaluates two pieces of code in separate runs, but using a common scope
-- `rhai_runner` runs each filename passed to it as a Rhai script
-- `simple_fn` shows how to register a Rust function to a Rhai engine
-- `repl` a simple REPL, see source code for what it can do at the moment

 Examples can be run with the following command:

 cargo run --example name
 ```
 
 ## Example Scripts
+
 We also have a few examples scripts that showcase Rhai's features, all stored in the `scripts` folder:
-- `array.rhai` - arrays in Rhai
-- `assignment.rhai` - variable declarations
-- `comments.rhai` - just comments
-- `for1.rhai` - for loops
-- `function_decl1.rhai` - a function without parameters
-- `function_decl2.rhai` - a function with two parameters
-- `function_decl3.rhai` - a function with many parameters
-- `if1.rhai` - if example
-- `loop.rhai` - endless loop in Rhai, this example emulates a do..while cycle
-- `op1.rhai` - just a simple addition
-- `op2.rhai` - simple addition and multiplication
-- `op3.rhai` - change evaluation order with parenthesis
-- `speed_test.rhai` - a simple program to measure the speed of Rhai's interpreter
-- `string.rhai`- string operations
-- `while.rhai` - while loop

 Finally, we call our script.  The script can see the function and method we registered earlier.  We need to get the result back out from script land just as before, this time casting to our custom struct type.

+In fact, any function with a first argument (either by copy or via a `&mut` reference) can be used as a method-call on that type because internally they are the same thing: methods on a type is implemented as a functions taking an first argument.

+```rust
+fn foo(ts: &mut TestStruct) -> i64 {

 Similarly, you can work with members of your custom types.  This works by registering a 'get' or a 'set' function for working with your struct.
