Code blocks



Like a Python, 11l uses whitespace indentation to delimit code blocks:
F sum(a, b)
   R a + b
[This code defines a function 
sum
, which returns a sum of its arguments.]

But 11l also supports explicit blocks designation via curly brackets, which makes it possible to define the same function without indentation:
F sum(a, b)
{
R a + b
}

or in one line:
F sum(a, b) {R a + b}

And this style is also supported:
F sum(a, b) {
   R a + b
}

And this:
F sum(a, b) {
R a + b
}

And this:
F sum(a, b)
{
   R a + b
}
