[plt-scheme] Borrowing #' aka quote-syntax
A good old trick is to rebind quote:
Welcome to DrScheme, version 360.2-svn29nov2006.
Language: Pretty Big (includes MrEd and Advanced Student).
> (let-syntax ([quote
(lambda (stx)
(display "foo\n")
(syntax-case stx ()
[(_ datum) #''datum]))])
(list 'abc '(1 2 3)))
foo
foo
(abc (1 2 3))
Today I wanted to borror #' for my own purpose, so I tried
the same trick:
> (let-syntax ([quote-syntax
(lambda (stx)
(display "foo\n")
(syntax-case stx ()
[(_ datum) #'42]))])
(list #'abc #'(1 2 3)))
(.#<syntax:22:12> .#<syntax:22:18>)
The first syntax-object contains abc and the other (1 2 3).
Is this intended?
