Are there any noteworthy lisp dialects that don't have macros?
Macros aren't obligatory, but I'm struggling to think of any good lisp examples that lack them.
Shower thought: Smalltalk (and to some extent other OO languages) replace pattern matching with dynamic dispatch.
I miss pattern matching in Lisp dialects without a good implementation, but I haven't noticed its absence in Smalltalk.
