#### 3.21`` Syntax Quoting: quote-syntax

> syntax (quote-syntax datum)

Similar to quote, but produces a syntax object that preserves the lexical information and source-location information attached to datum at expansion time.

Unlike syntax (#'), quote-syntax does not substitute pattern variables bound by with-syntax, syntax-parse, or syntax-case.

Examples:
> > (syntax? (quote-syntax x))
> #t
> > (quote-syntax (1 2 3))
> #<syntax:72:0 (1 2 3)>
> > (with-syntax ([a #'5])
> (quote-syntax (a b c)))
> #<syntax:73:0 (a b c)>
