Discussion on: We created the Crystal language, ask us anything!

[Brian J. Cardiff]

Some things that bugs me a little bit in the language are:

1. the lack of variance in generics.
2. that some types can be expressed thanks to macros but not in the grammar (difference / substraction of types)
3. that / should always be float division (instead of depending on the receiver/argument types).
4. that the grammar type can't be blend with the language grammar.

So I am pretty happy with the language :-)

From the ecosystem, there are some stories to be improved in dependency management and development tools.
