? this is an example of a comment
  this is the second line of the comment
  as long as the line starts with indentation
  the line is the part of the comment

? following is the semantics of:
  - call a function
  - save the result in a variable
  - give the function keyword arguments
  - give the function positional arguments
  - give the function options to jump to next function node

- parent node
  = save variable
  @ keyword1 argument
    + value of keyword argument 1
  @ keyword2 argument
    + value of keyword argument 2
  + function call
    + function argument 1
  + argument 1
  + argument 2

? following is the semantics of:
  - chain execution of multiple nodes if first possible node

- parent node
  + argument 1
  - execute node 1
    + argument 1
  - execute node 2
    + argument 1

? following is the semantics of:
  - creating a custom function node
  - declaring the keyword arguments of the function node
  - declaring the positional arguments of the function node
  - creating the execution logic of the function node
  - setting the return value of the function node
  - selecting the next node to execute

* custom node
  @ custom name 1
  @ custom name 2
  @ custom name 3
  + argument variable 1
  + argument variable 2
  - execute node
    + argument 1
    + argument 2
  - execute node
  - execute node
  = set return node (value)
  : set return path (number)

? following is the semantics of:
  - declaring a literal type that is text
  - assigning a value to that variable

! text value
  = variable name

? following is the semantics of:
  - declaring a literal type that is not text
  - assigning a value to that variable

- literal type
  = variable name
  ! value

? following is the semantics of:
  - importing a material
  - materials are node overloads for:
    - performing actions
    - connecting to external systems
    - providing utility functions
    - be like a library / imports

$ material imports

$ material imports with prefixes and suffixes
  @ prefix
    + text
      ! material
  @ suffix
    + text
      ! imports

? following is the semantics of:
  - control flow powered by node definitions
  - special function sets value of return node
  - return node is an integer
  - it works normally, plus ability to decide the next node

- special function
  > path 1
  > path 2
  > path 3
