Please re-read what I said. I never claimed it was easy to port in every situation.

I merely pointed out that "depending on what you are doing they (semantic differences) are minor considerations." and then gave an example where that was the case with a simple application I was working.

If you want a more complicted library that was ported from Ruby to Crystal then you can also look at Sidekiq ( https://www.mikeperham.com/2016/05/25/sidekiq-for-crystal/ )

But when this doesn't apply to even basic parts of the Ruby ecosystem, like Active Support, these 'minor differences in some cases' are fundamental showstoppers for a company like Shopify, which was the context.

The original comment said 'without needing to really think in a whole different programming experience'. Ruby without #send and #eval is a very much a whole different programming experience for a company like Shopify.
