Intro

Introduction to the Syntax section
Syntax
Drizzle's source code can can be written in anything up to Unicode, due to Crystal's ability to handle Unicode code-points in it's char type.
The language is currently in an initial design phase, so all the docs in this section are subject to change at will until the implementation begins.
Example
Here is a brief example of the Drizzle code as it is currently planned to look.
If any specifics change in this section that affect this example, the example will also be updated.
# Also allows double quote strings
​
# Function definitions
# `num` is a type alias that allows both int and float types to be used
def add(a: num, b: num) -> num {
    return a + b
}
​
# Fibonacci function
def fibonacci(x: int) -> int {
    if (x == 0) {
        return 0
    }
    elsif (x == 1) {
        return 1
    }
    else {
        return fibonacci(x - 1) + fibonacci(x - 2)
    }
}
​
# Drizzle supports higher order functions, i.e. functions that take other functions as parameters
def run_twice(f: ((num) -> num), x: num) -> num {
    return f(f(x))
}
​
def add_two(x: num) {
    return x + 2
}
​
println(run_twice(add_two, 2)))  # Should print '6'
