Hello schemers!
R6RS specifies an inline hex escape syntax for symbols. These do not
work in Guile 2.2.3:
scheme@(guile-user)> (read-enable 'r6rs-hex-escapes)
$1 =3D (square-brackets r6rs-hex-escapes keywords #f positions)
scheme@(guile-user)> (symbol->string '\x7c;
)
$2 =3D "\\x7c"
I expected this to return "|".
While fixing this, perhaps it would also be possible to add recognition
of #!r6rs to set the appropriate per-port read options, similarly to how
#!fold-case is recognized? It would make it much easier to load R6RS
code in Guile.
Best Regards,
