Current Limitations

Alpha-7 is an early development release.

The following features are not currently fully implemented in the backend:

Data declaration code generation
Object instantiation code generation
Deal remains reserved for possible future pattern-matching syntax; implemented Switch statements use Case and Base
Error handling in the Cranelift backend
Windows top-level uncaught-error printing
Finally handling for Stop and Skip
Package and dependency management
Complete lexical scope handling
Multicore Sydrogen program execution
Garbage collection
Self-hosting Furnace
Complete systems-level standard library

Some of these features are already represented in the grammar or AST.

There is an important distinction:

Parsed means Furnace can recognize the syntax.

Semantically checked means Furnace can inspect the construct and report certain errors.

Code generated means Furnace can produce executable native code for the construct.

A feature being parsed does not mean that it can currently be used in an executable program.

This distinction saves everyone from discovering that the compiler supports something only after the compiler politely refuses to compile it.
