Comment on A brief introduction to OCaml parent

The idea is you can write this:

let _ = print_string "foo"

let _ = print_string "bar"

at the top level.

Ah. Well, the solution is not use "let _" or ";;", the solution is to avoid sociopathic code like that. Module definition with built-in, unavoidable side effects are evil.

You need at least one module that does something at top-level, otherwise your program won't do anything.

For serious development, yes, but consider the people who are learning OCaml. One of the first programs is going to be some kind of side effecting hello world etc.
