I have tried the coil command and tested the case you mentioned above. I found
some bugs and fixed it. Now the conversion of pipe seems to work well after
several tests. But as is said in the Project Idea page [1], the pipe primitive
only works with certain parameter settings. What does it mean? What settings
cannot be dealt with before?
