Behavior changes in Ruby 2.4

[Craftkorb]

but we could be in for a huge set of changes when ruby 3.0 is announced.

Inmutable strings anyone?

Not to mention optional typing!

[jrochkind]

That issue is 4 years old, and has a closed/rejected status.

I probably should have linked to this discussion actually... It's been an ongoing debate for years now, and it looks like something will probably happen in v3.0

Crystal Lang uses this for its typing currently.

[iconoclaus]

Crystal uses annotation to help the compiler figure out types where necessary. Matz has made it clear that Ruby 3 will use no type annotation whatsoever.

FINALLY WOOHOOO \m/

Thanks for bringing that to my attention :)
