I was 7 when I started writing simple programs (to solve simple equations which came up in maths class) in QBasic. I was 8 when I learned about arrays, which led to writing a contacts app (storing name, address, and phone number in a file, then reading it and displaying the info). It took crazy amounts of time and incredible number of trial and error, but it was fun. Not sure if I'd be able to pull off the same at 5, but it doesn't strike me as utterly impossible. Also, the GP didn't say what was the result of his "serious coding" - could be nothing (working) at all until much later.
