Not indenting code

Just because you don’t have to indent code blocks with whitespace, doesn’t mean you shouldn’t. Indenting blocks of code aids readability and makes the intent of the scoping clear.

Anti-pattern

function myfunction()
if condition()
println("condition met")
end
end

Best practice

As a general recommendation, indent blocks of code with 4 spaces.

function myfunction()
    if condition()
        println("condition met")
    end
end

The exception is module blocks which are usually not indented as they often correspond to whole files.
