10 Preserving Source Locations
|(require syntax/quote)||package: base|
The syntax/quote module provides support for quoting syntax so that its source locations are preserved in marshaled bytecode form.
(quote-syntax/keep-srcloc #:source source-expr datum)
Like (quote-syntax datum), but the source locations of datum are preserved. If a source-expr is provided, then it is used in place of a syntax-source value for each syntax object within datum.
Unlike a quote-syntax form, the results of evaluating the expression multiple times are not necessarily eq?.
