Re: Any more bugs/typos?

*Vladimir Nikishkin*17 Sep 2020 07:22 UTCThis is an optional procedure anyway. The specification does not prohibit the implementation from implementing proper Bezier curves. "It is not an error to supply more than one <code>vecI</code>, but this SRFI does not specify an exact behaviour." is what the latest draft says.
