It makes no sense to me. Even in math notation where one-letter names and terse notation are the norm, you rely heavily on familiarity and convention to understand the notation. Reading a computer program written in such terse style is like reading a textbook in a completely unfamiliar field, without a symbol glossary or explanatory text. The cognitive burden can be extreme. I do agree that there is some value in higher information density and the ability to quickly "pattern match" on sections of code (eg. regex), but only up to a point.
