A functional programming language with pipelines, pattern matching, and effect handling

use core.io!;

[1, 2, 3, 4, 5]
    |> filter(x => x % 2 == 1)
    |> map(x => x * x)
    |> reduce((a, b) => a + b, 0)
    !> io.println;  // 35

Features

  • Pipeline Operator (|>) - Chain function calls in a readable left-to-right style
  • Effect Pipeline (!>) - Chain side-effecting functions with automatic result wrapping
  • Pattern Matching - Powerful match expressions for control flow
  • First-class Functions - Lambda expressions and closures
  • Constraints - Define and enforce value validation rules
  • Result Types - Built-in success(value) and failure(error) for error handling
  • Module System - External module support via Boneyard registry
