New Feature: Built-in and custom decorators

[Buscedv]

Decorators

The ability to "insert" both built-in (part of Ask) and user-made code/functionality into functions.

Usage

Decorating a function and/or route

&[decorator goes here]
def [function]([params]): # OR: @[method]([route]): 

Creating a decorator

decorator [decorator name goes here]:
  # Code goes here...
  ...

Simple Example

decorator my_first_decorator:
  print('Before')
  _inner()
  print('After')

&my_first_decorator
def my_function(message):
  print(message)

my_function('Hello')

Transpiled result

...

def my_first_decorator(func):
  def wrapper(*args, *kwargs):
    print('Before')
    func(*args, *kwargs)
  return wrapper

@my_first_decorator
def my_function(message):
  print(message)

my_function('Hello')

...

Output

Before
Hello
After

Ideas

• Built-in decorator names should start with: _, e.g. _a_built_in_decorator.
• See issue #35 & #25 for more examples.

Can I do that by creating a template_dict that will store lambda function ?
And a function will call this template if he finds his name as a key inside ?

I think lambdas might be a bit too simple in this case. I would like to make multiple line/function/class templates, basically, whole parts of scripts and that would be really hard to implement with single-line lambdas.
What I had in mind was to generate decorator & first-class functions to achieve this.
