If N is known to be non-nil, e.g., a glyph node, is it save to call node.insert_after(nil, N, x) ? If the answer is 'Yes', I propose re-ordering parameters of function node.insert_after (and node.insert_before), so that head can be easily left out in the function call: function node.insert_after(<new>, <current>, <head>) Best regards, Stephan Hennig
