I'm going to mildly object to the characterization of print and log 
debugging as "lazy". I've spent plenty of time in debuggers over the 
years and in many cases I just prefer a simple print over stepping 
through a huge number of lines of code. Both debugging techniques have 
their place and nobody should feel bad because they chose one over the 
other.

I've starred it. It looks a bit like bash's xtrace on steroids, which is 
something I use quite a lot when debugging bash scripts.
