Technical problems I have with logging: it is manual in that I cannot just turn on logging for lines 345-387, or for function doTheThing(), I have to add log statements and monitor wherever they are output (or even set up their outputting). For compiled languages this seems like a tough problem to solve. For interpreted languages to deny me this feature is a slap in the face.
