Here is Dijkstra: http://www.u.arizona.edu/~rubinson/copyright_violations/Go_To_Considered_Harmful.html First statement: | For a number of years I have been familiar with the observation that | the quality of programmers is a decreasing function of the density of | go to statements in the programs they produce. And here is Hoare, not identical to Dijkstra but with similar areas of interest and similar views on correctness etc, very unambiguously criticising exceptions: | Ada has a plethora of features and notational conventions, many of them | unnecessary and some of them, like exception handling, even | dangerous. Do not allow this language in its present state to be | used in applications where reliability is critical http://en.wikipedia.org/wiki/Exception_handling#Criticism -- https://mail.python.org/mailman/listinfo/python-list
