The developer in me thinks this is nuts. Run the same few lines of code twice, with no changes in between, and get different outputs? Madness!
Here’s another example. Nothing too complex here: I connect to an instance of SQL, SELECT CURRENT_TIMESTAMP, and show the returned value in the output window. (There’s a fixable issue here that I would go on to discover later. But hold that thought for now.)
Even when you’re conceptually familiar with a language, getting into the particular foibles of that language can expose all sorts of behavior which is strange to newcomers.
