This release sees significant improvements for use with non-latin characters in both the interactive prompt and shell scripting. It introduces new syntax to make working with structured data even easier than before. As well as new data types and smoother user experience.
$PWD is no longer a str. If you need to
parse $PWD as a string then you should
out: $PWD or use ${pwd}. is now a valid bareword character for variables.
This will break any instances in code that contain something like
out $hello. however you can now use
out $(hello). syntax for safer string infixing$json.array.index$() to
avoid variable barewords from leaking into other values when infixed. eg
$(foobar) is the same as $foobar (read more)$(比如) = "举手之劳就可以使办公室更加环保，比如，使用再生纸。"
