Expressions

Zirric is expression-first: most constructs produce a value. This document
captures the base language surface described in proposals/ZE-001-base-language.md.

Literals

42                 // Int
3.14               // Float
0x8899aa           // Hex Int
0777               // Octal Int
0b101010           // Binary Int
1e10               // Scientific Float
true               // Bool
false              // Bool
"Hello, World!"    // String
[1, 2, 3]          // Array
{ "key": "value" } // Dict
{ a, b -> a + b }  // Function literal
                        

Operators and precedence

Operators marked as reserved are part of the base language proposal but may not
be implemented yet.

let value = object.field + 2
fun(x + 1, y * 2)
                    

Calls and member access

Calls use name(args...). Member access uses . and reads fields off data
instances or extern values.

let p = Person("Alice", 30)
print(p.name)
                        

Function literals

Function literals are written as { params -> expr }. The body is a single
expression.

let add = { a, b -> a + b }
add(1, 2)
