> The thing that mathematicians refuse to admit is that they are extremely sloppy with their notation, terminology and rigor.
The refuse part is imo ver dependent on the person. Nearly all of my professors for theoretical cs courses just plainly said that their "unique" notation is just their way because they like it.
It's more or less just a simple approach to alter the language to fit your task. This is also not unfamiliar to the programmers who may choose a language based on the task, with, e.g. Fortran for vector based calculus or C for direct hardware access.
