Oh god yes, I was bitten by almost this just a few days ago, except my
code was:

  open Printf
  open Format
  
  (*...*)
  printf "I'm trying to debug something\n"

(The file was quite literally not more than 15 lines long, but it took
me a good hour to work out why that printf wasn't printing anything ...)
