My own preference would be something like [3 instead of #A3(
Let's not invent new confusing syntax when we have existing confusing syntax that is just as good ... Array syntax should be compatible with Common Lisp's notation. Anything else requires a *really* strong justification. If you want to *extend* the Common Lisp syntax with a type specifier, that is ok. But that should be done with type specifiers. So don't use crypic abbreviations; use type names that can form the basis for optional type specifiers. (See below for more on this.) Suggestion 1: A two-by-two array of unsigned 16-bit integers: #2a:int16((0 1) (2 3)) Suggestion 2: Many Scheme use <TYPENAME> by convention for class- an/or type-names. We could incorporate this syntax: #2a<int16>((0 1) (2 3)) I agree with the goals of srfi-58. Unfortunately, it builds on srfi-47, which I don't care for. I'd prefer: (make-array <element-type-specifier> elements ..) where an <element-type-specifier> might be something like <int16>. Then we could add optional static typing: (define i1 :: <int16> 1) ;; or: (define (i2 :: <int16>) 2) ;; alternative syntax (make-array <int16> i1 i2) Kawa implements part of this, mapping Scheme type specifiers to Java classes or primitive types. We'd want an array type specifier too, perhaps <arrayN:ELEMENT-TYPE>: (define arr1 :: <array2:uint16> #2a:uint16((1 2) (3 4))) -- --Per Bothner per@xxxxxxxxxxx http://per.bothner.com/
