This section is for snippets that I have no idea where to put, but I feel they should be included somewhere.
In Luna the precedence of operators depends on whether they are surrounded by spaces. Operators not surrounded by whitespace always bind stronger that those with spaces around. For example 2 * 2 + 2 gets interpreted as (2 * 2) + 2, but if we remove the whitespace around + like so: 2 * 2+2, it becomes 2 * (2 + 2).
It's particularly useful with long chains of method calls. The expression:
([1, 2, 3].map (+ 1)).sum
can be rewritten as:
[1, 2, 3] . map (+ 1) . sum
resulting in a much cleaner code, without unnecessary parentheses.
