left-to-right

The arc version has to be read from the inside-out, vs left-to-right in ruby.

So you have one line per server, going left-to-right, shading from white (for no errors) to whatever color (for the maximum number of errors overall).

The SQL version reads left-to-right, similar to how ReQL's version reads top to bottom, and both reflects the execution order (in terms of a common way of text flow).

Its look depends on the OS, OS version, OS theme, OS scaling setting, OS font settings, the language (left-to-right, right-to-left).

I always read s-expressions left-to-right.

"Here be electric magic." - If you ever implement generic functions dispatched left-to-right, you can implement partial dispatch for partial application.

Stating that function arguments evaluate left-to-right, just like "operator," does in expressions, would be an infinitesimal speed hit on strange systems, and no speed hit at all on modern systems that can just as easily use an indirect move to set up the stack frame.
