Likewise, some people love the ABC and Python model of syntactically important leading whitespace while others passionately prefer some sort of brackets (for this purpose brackets include parentheses, curly braces, square brackets, words like BEGIN and END, etc).

Some love short, mnemonic built-in variables and short built-in function names of the sort you see in APL or Perl (although Perl has longer-named versions optionally for a lot of things). Others love long, self-documenting names for keywords and functions. They might want no built-in variables at all.
