描述

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?

研究方向
Investigate the CoffeeScript grammar definition for class declarations, likely in the 'src/grammar.coffee' file. Review existing implementation of class methods and understand how properties could be added. Read through the 24 comments on the issue to understand proposed syntax and semantics, and check for any linked issues or PRs that discuss property initializers.
