As someone mostly using compiled programming languages, I am perplexed about the built-in types that this new language provides. According to https://typespec.io/docs/standard-library/built-in-data-types https://typespec.io/docs/standard-library/built-in-data-type...: * unixTimestamp32, but no 64-bit version * plainDate that can be "April 10th" without the year * DefaultKeyVisibility, OmitDefaults.. what? I am genuinely curious how did that happen. Design by committee? Some secret use cases that leaked into specification?
