For example the terse style of Sexpressions or C-style braces are off putting to some but after a short while they become second nature to visually parse (not saying all code should follow Those idioms, just using that as an example of how readability changes with experience). On the other hand I never found it as straightforward visually parsing the “word soup” of named arguments when using languages that favoured it. While those languages were easier to learn the basics, they quickly became tiresome to write larger code bases with.
But I guess this just boils down to personal preference.
