// ChaiScript supports the normal kind of control blocks you've come to expect from 
// C++ and JavaScript


if (5 > 2) {
  print("Yup, 5 > 2");
} else if (2 > 5) {
  // never gonna happen
} else {
  // really not going to happen
}

var x = true;

while (x)
{
  print("x was true")
  x = false;
}

for (var i = 1; i < 10; ++i)
{
  print(i); // prints 1 through 9
}


// function definition

def myFunc(x) {
  print(x);
}

// function definition with function guards
def myFunc(x) : x > 2 && x < 5 {
  print(to_string(x) + " is between 2 and 5")
}

def myFunc(x) : x >= 5 {
  print(t_string(x) + " is greater than or equal to 5")
}

myFunc(3)

// ChaiScript also supports in string evaluation, which C++ does not

print("${3 + 5} is 8");

// And dynamic code evaluation

var value = eval("4 + 2 + 12");

// value is equal to 18

Line 39 should be "to_string(x)"
