This library is deprecated; use the
[paren-shape pattern expanders][stxclass-paren-shape] from
syntax-classes-lib instead.
Racket pattern expanders for dealing with paren-shapes in syntax-parse macros
```racket
> (require syntax/parse paren-shape/pattern-expander)
> (syntax-parse #'(1 2 3)
[(~parens a b c) #'a])
#
> (syntax-parse #'(1 2 3)
[(~brackets a b c) #'a])
;expected list or pair surrounded by square brackets in: (1 2 3)
> (syntax-parse #'[1 2 3]
[(~parens a b c) #'a])
;expected list or pair surrounded by parentheses in: [1 2 3]
```
