macro

Custom precedence of custom operators is a first class citizen and key feature of the angle programming language. It makes many macros unnecessary and instead allows building elegant code from first principles.

So the if condition could be implemented entirely clean via:
IF(condition:block then:block else:block?) = condition and then or !condition and else
(safe for some syntactic sugar such as if 1:2 == 2

block, code and closure are very similar concepts:

• every data with the intention of being evaluated is a block
• every block with concrete binding is code
• every code with a local-only binding is a closure
