Description

We should be able to write the equivalent of

class C {
  b = 3;
  c = () => 4;
}

Can it be

class C
  b: 3
  c: () => 4;

or does the b property have different semantics?

Contributor guide

Research direction
Investigate how CoffeeScript's class body currently works and implement support for property initializers with assignment syntax (e.g., b = 3) or colon syntax, ensuring semantics match JavaScript class fields where appropriate.
