You could build your own way of passing "dynamic" parameters to the constructor, but most of the times if you need too many arguments for a constructor you might be needing to introduce a new abstraction, so take it as a sign to reify something. Syntax sugar in Smalltalk most of the times comes from better abstractions, not from the language's syntax.
