I just did something that depending on your viewpoint on coding, is either an insult to God and humanity, or absolutely brilliant.
#
# I inherited a large code base, where hundreds of code paths end up
# calling "common_function_called_in_gazillion_places".
#
# And the need arose for this function to access the HTTP request's
# headers...
#
# What to do? Refactor all the places leading up to here? In a dynamically
# typed language, with no compiler to tell us the places to refactor?
