Amir on why they didn't go with crystal

That's a bit light on the details, and I can't make any sense of "To use stdio even you literally need kernel-level privileges on Console.", C's stdio doesn't require special privileges to use, nor does Crystal's, afaik.

Maybe someone else will know that means.

I think Console is as in XBox or PlayStation, not as in the kind of application.

Ah, the use of Germanic uppercased nouns in English sent me the wrong way. Thanks.

More poignant examples would be `dirent.h` and `system`. Getting access to the file system on a console, or the ability to start up a process out of band is not allowed.

Which task? DragonRuby uses a custom mruby build to target cross platform game releases so their goal is to fit the Ruby lang spec, which Crystal does not adhere to.

> their goal is to fit the Ruby lang spec

I honestly thought that "ruby lang spec" was "whatever Matz ruby does." The ISO-IEC-30170 standard cited by mruby's readme seems to be laughably old but I can't obviously tell if mruby is a superset of the ISO or a subset. Their use of the phrase "part of the ISO standard" doesn't help

Matz is the creator and maintainer of Ruby, yes. mruby is a subset to my knowledge, and I don't think it's 100% parity with Ruby MRI (CRuby), which is basically what the lang spec is built around to my knowledge.

There's a full blown test suite for Ruby which the various implementations use: https://github.com/ruby/spec
