Neat 0.1.0: Lambdas, IFTI, Ranges

Lambdas

Lambdas are templated nested function references:

auto lambda = a -> a * 2;

IFTI

When calling a template like a function, the template
will be instantiated with the types of the arguments.

template each(Range, Callable) {
  void each(Range range, Callable callable) {
    for (value in range) callable(value);
  }
}
...
  each(2..4, a => print(a));

Ranges

Loops will now iterate over values with a fixed protocol.

  for (a in range) { }
  // --------------
  // is the same as
  // --------------
  mut auto iter = range;
  for (mut ElementType a = iter.front; !iter.empty; iter = iter.next) { }
