[SUGGESTION] Question: Why 'a function must have a body'?

[jazn]

I found that cppfront requires class function to be defined in declaration. (https://github.com/hsutter/cppfront/blob/main/source/sema.h#L1076)
In c++ definition and declaration are more independent.

I wonder why this constrain exists?

UPDATE:
I have a basic (simple?) problem: how can I include a cpp2 header with class definition in two .cpp2 files and link them together. I will get 'multiple definition' error on linking.

Cpp2 function bodies are order independent.
So their relative order in a source file doesn't matter.
The README mentions:

An alternative syntax would let us do things we can never do within today's syntax without breaking the world:

• [...]
• make it easy to write refactoring and other tools (e.g., have order-independent semantics).

UPDATE: I have a basic (simple?) problem: how can I include a cpp2 header with class definition in two .cpp2 files and link them together. I will get 'multiple definition' error on linking.

This problem was brought to light by the discussion at #594.

Thanks for pointing that out.
