L (for LENGTH) does exist as a property of a "constructed curve" - maybe that can help while waiting for a new function? Scan a circle segment, construct the exact endpoints by intersecting the circle with lines on the sides, create a set of <startpoint, all hits from the scan, endpoint>, create a curve from the set. Output CURVE1.L
