Feature Progress

Decide which keywords are absolutely necessary
Create keyword types and tokenization rules
- else
- for
- fn
- if
- in
- let
- while
- match
- ...

Feature description

Keywords are reserved identifiers with special meaning, which combine with other language elements to produce a unique effect.
Examples of keywords in other languages:

if, else, match, switch: conditional control flow
fn, let: starts a declaration
try: marks the next expression as potentially containing fallible elements
...

Example

// Example is in (unstable) Rust; Conlang currently has no keywords, block expressions, or control flow
fn main () {
    let x = try {
        something_fallible?;
    };
}
