 This is a fair point.

 I'm not entirely sure this is an apples-to-apples comparison though.
 Python and Ruby are both interpreted languages with no real compile-/run-
 time phase distinction and certainly no "batch" compilation.

 In the case of C++ you rarely invoke the compiler itself; instead you
 typically invoke it via some build system, most of which do provide per-
 module feedback on progress. The same holds for most Scala and Java build
 systems, as far as I know.

 Of course, none of this is to say we shouldn't reconsider our output.
