# (* i am just a comment. nobody cares about me. oh wait! *);;
# Error: Parse error: illegal begin of top_phrase

I am getting this error

Error: Parse error: illegal begin of top_phrase

when I am try to enter a comment in the interpreter. Are comments not allowed in ocaml interpreter or am I doing something wrong?

Answer 1

I'd say you're entering nothing at all, which is a syntax error.

# (* Hello *) ;;
Error: Syntax error

Try entering something after the comment:

# (* Hello *) 3 ;;
- : int = 3
