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]

```
