Readonly sugar #4

Closed aleclarson closed 5 years ago

WDYT of adding sugar for readonly properties (or even objects/arrays)?

I like Flow's + syntax.

Everything in the language will be immutable unless marked otherwise, there is currently no way to mutate values in Ghost

@jamiebuilds Can I assume generators will be immutable, too? (so no need for libraries like https://github.com/pelotom/immutagen)

Ghost doesn't have "generators" as they are in Python and JavaScript. Ghost has "iterable functions" and yield does not wait for a value to be passed to iter.next(value).

As such iter.next() is idempotent (and immutable).
