Imagine discussing math and programming with someone who insists that pi=3 and GOTO is the best control flow mechanism.
a) A friend made their pile developing Atari 2600 cartridges. In those days, doing a pythagorean distance calculation would've been way too expensive (especially as they had to work in between scan lines), so in their programs hit regions were octagonal, which is not pi=3, but not far off from pi=6.
b) As someone who generates object code, GOTO is the best control flow mechanism in that domain. [see also "Lambda: the ultimate GOTO" (1977) https://dspace.mit.edu/handle/1721.1/5753 ]
