adding goto to Python
|
|
goto is one of the fastest computer programming operations around, at least if we don't actually use it. what if Python had a goto statement/keyword?

Python would have lot of spaghetti code (this is not my opinion but BDFL himself):

noop is much safer than goto.

I would probably still program Python, but I would not be on this board. If Python had goto, newbies would use it all the time, they would use it wrong all the time, and we would spend all our time fixing goto issues. No thanks.

Goto statement in Python could be and is already implemented by bytecode-injection; You can try it by installing goto-statement module. So, if someone wish, they can install it and take a feeling how to write code in Python with
goto statement. Note, that goto-statement is a joke module, don't use it when doing something worth.

I personally admire many of Dijkstra's writings due to his ability to explain in spoken language fundamental challanges in programming.

In case you want to actually use it, there was an April fool's module written which adds goto support for python:
http://entrian.com/goto/ However, it is NOT fast. The way it works, is it installs an exception handler, and when a syntax error is raised for "goto" (since that's not a real keyword), it redirects the debugger to continue execution at the specified label. |
