Goals 🐕

• Light to write (inspired by Ruby)
• Strongly and statically typed
• Native code efficiency
• OOP
• Immutability-aware
• Familiar with functional features
• Dog-friendly

# If 'var' is specified, the argument is copied and passed by value
# then mutable.  Otherwise, the argument is passed by reference then
# immutable. Variable definition has the same rule as this.
# Type of arguments and returned value are deduced automatically.

# If you want to specify the type of argument, you can use ':'.
# e.g.
#   func step_to(var first : float, last : float, block) : ()

func step_to(var first, last, block)
    for first <= last
        block(first)
        first += 1
    end
end

# UFCS is implemented.
# '1.step_to n' is equivalent to 'step_to(1, n)'

# Dachs has a block inspired from Ruby.
# do-end block is passed to the last argument of callee as lambda object.
# Here, 'block' variable is captured into do-end block.

func fizzbuzz(n, block)
    1.step_to n do |i|
        case
        when i % 15 == 0
            block("fizzbuzz")
        when i %  3 == 0
            block("fizz")
        when i %  5 == 0
            block("buzz")
        else
            block(i)
        end
    end
end

func main
    fizzbuzz 100 do |i|
        println(i)
    end
end

# Array and tuple are available as container.
# (dictionary will come.)
