| Date: Sat, 01 Jan 2005 19:14:15 -1000 (HST) | From: Shiro Kawai <shiro@xxxxxxxx> | | srfi-58-new.html has an example: | | (array-dimensions #2A:integer+16((0 1 2) (3 5 4))) ==> (2 3) | | Do you suggest arrays are self-evaluating objects, or a quote is | simply missing before the array literal? The quote was missing. I have expanded that section to: A two-by-three array of nonnegative 16.bit integers is written: #2A:integer+16((0 1 2) (3 5 4)) Note that this is the external representation of an array, not an expression evaluating to a array. Like vector constants, array constants must be quoted: '#2a:INTEGER+16((0 1 2) (3 5 4)) ==> #2A:integer+16((0 1 2) (3 5 4)) | I also assume literal arrays are immutable, like literal strings | and vectors, right? Although the immutability is implied from | R5RS section 3.4, it may be nice to have it explicit in srfi-58, | since I see modifying literal values is a common type of errors. Thanks for your suggestions. I have added the paragraph: Literal array constants are immutable objects. It is an error to attempt to store a new value into a location that is denoted by an immutable object.
