Worse, I've seen a lot of code that just uses the variable name "ll" as an array of two numbers and make no attempt to clarify which is which. Saved a whole 4 characters by not making it "latlon". Then you get to guess what units they're in.
If it’s a variable there’s a reasonable chance it’s used more than once and thus saves more than four characters.
Maybe your text is grey cause saving a few chars on variable names doesn't save any RAM. And also confuses sober-you from reading your own code.
This is also why I avoid indentation; programming is all about saving those precious bytes like it’s 1988.
On top of this, I feel like `ll` is quite verbose and memory intensive. A simple `l` would suffice with half the space.
`l` needs practically twice as many hole punches as `a` for "array" in my EBCDIC punch cards and fewer punches is less likely a card gets shredded in the reader.
