Boo is an object oriented, statically typed programming language in active development since 2003, which seeks to make use of the Common Language Infrastructure's support for Unicode, internationalization and web applications, while using a Python-inspired syntax and a special focus on language and compiler extensibility. Some features of note include type inference, generators, multimethods, optional duck typing, macros, true closures, currying, and first-class functions.

Boo is free software released under an MIT/BSD–style license. It is compatible with both the Microsoft .NET and Mono frameworks.

Code samples

Hello world program

print "Hello, world!"

Fibonacci series generator function

def fib():
    a, b = 0L, 1L       #The 'L's make the numbers 64-bit
    while true:
        yield b
        a, b = b, a + b

# Print the first 5 numbers in the series:
for index as int, element in zip(range(5), fib()):
    print("${index+1}: ${element}")
