In Smalltalk, the 'keywords' are actually part of the method name; when you say '1 to: 10 do: [ ... ]', you're not calling to: on 1 (which is an entirely different method) with a keyword argument, you're calling to:do:. > This shared syntax makes the language read better. It makes function calls and keywords look like a normal infix language (e.g. the math expressions in most languages). Ironically, since Smalltalk also applies this uniformity to arithmetic operators, they don't behave how most people would expect: a + b * c - d is executed like (((a + b) * c) - d).
