Most features on the tour page are currently implemented to varying degrees. Below is a rough list of features being worked on.

Near Future

• Language Server: Better support for struct members and methods
• Inserting drop automatically after a variable’s last use
• Default handlers for Panic, Print, and some other effects in main
• Renaming of the Fs, Net primitive effects
• Compiler option to write inferred types into the file
• Formatter
• Rework or removal of ~> operator for effect handling

Futurer

The following features are unimplemented but are not my top priority to implement in the near future.

• Design & impl of a comptime system enough to write your own derives but also cached by the compiler’s incremental metadata
• Char is 1 byte rather than 4 currently. There is an open design question of whether Ante should use Rust’s model for chars (4 bytes), Swift’s model (variable bytes), or something else.
• Bit shift functions
• Pattern guards such as | pattern if expr -> ...
• Performance guarantees on for_ to be as fast as the native for loop
• A check to ensure only pure implicit functions can be called implicitly
• Row-polymorphic struct types
• Cranelift backend
• Language Server: Fill in match arms action
• Proper unwinding when resume is dropped
• Modules: as name, re-exports, import implicit
• Marker type on each trait impl
• Rework of closure types
