don’t have to learn about indenting until you cover flow control
Which is one of the very first things they're taught - "hello world", variables ("Enter your name", "hello {name}"), branches, and loops, in that order.
I’m not sure I can think of a language that would be better suited to learning
Pascal - it's what it was designed for. Variables, branches, and loops, with strong types and optional indenting. Once people have a handle on that, THEN move onto OOP.
