ArkScript v4.3.0

Breaking change

• in macros, len, empty?, head, tail, @ have been renamed to $len, $empty?, $head, $tail and $at. Those versions only work inside macros too, inside of having a weird dichotomy where they sometimes got applied and sometimes not

Added

• apply function: (apply func [args...]), to call a function with a set of arguments stored in a list. Works with functions, closures and builtins
• +, -, *, / and many other operators can now be passed around, like builtins. This now works: (list:reduce [1 2 3] +), where before we would get a compile time error about a "freestanding operator '+'"
• builtin__slice builtin, for strings and lists: (builtin__slice data start end [step=1]) ; this is an experimentation and may be removed in future versions
• arguments of builtin macros are properly type-checked and will now raise runtime errors if the type is incorrect
• -fno-cache cli option to disable the creation of the bytecode cache folder __arkscript__
• in the CLI, file can be - to read code from stdin

Changed

• when using the cli flag -fdump-ir, the IR is dumped in the cache folder
