v0.2.0 - Amaranth

Breaking

• Introduce new C-style comment syntax. # Example becomes // Example.
• Remove import * as Foo from "foo" syntax. Instead use import *, Foo from "foo".
• Change data type syntax to enum for variants and record for record types. Check out https://grain-lang.org to see these syntax updates!
• Renamed wasm files generated by Grain to .gr.wasm.

New

• Brand new Number system! Inspired by Racket's number system. Operations can be performed across number types, including rationals.
• Allow mutable (boxed) values with let mut syntax. This avoids the need to explicit boxing and unboxing in most code!
• Sourcemap support with a --source-map command line option.
• Added ++ operator for String concatenation.
• Support guards for pattern matching - e.g. Some(a) when a < 1.
• Support pattern matching on constants - e.g. match (a) { 1 => true }.
• Docker support which can be pulled from https://hub.docker.com/r/grainlang/grain.
• Many standard library improvements, including Option, Result, Map, Queue, tons of new methods, and cleanup.
• Exception support, but currently no way to create or catch them yet.
• Added isnt operator to check if things are not the same memory reference.
• Support trailing commas in data structures, like list, record, tuple, etc.
• Add an "LSP mode" to the command line for Grain Language Server.
• Block comment support - e.g. /* Example */.

Fixes

• Fixed cross-module type checking bug.
• Fixed & documented operator precedence.
