How can I break up this long line in Python?
...joining is that it only works with string literals, not with strings taken from
variables, so things can get a little more hairy when you refactor. Also, you can only interpolate formatting on the combined string as a whole.

Why do I get a segmentation fault when writing to a “char *s” initialized with a string literal, but
...stored in read-only memory when the program is run. This is to prevent you from accidentally changing a string constant. In your first example, "string" is stored in read-only memory and *str points to the first character. The segfault happens when you try to change the first character to 'z'.

Why doesn't Haskell's Prelude.read return a Maybe?
... good news is that folks were sufficiently convinced to start moving away from fail in the libraries. The bad news is that the proposal got lost in the shuffle.
