This should work in 5.3.9. I will fix the arrow ;)

No it is a bug, I will try to fix it.

Try this. It is copied from flag entrance code.

def p_entrance (expr pos,theta,sc,al)=
    U:=(.3u,.25u);
    T:=identity aligned al scaled sc shifted pos;
    pickup PenX;
    thdraw (-.3u,-.25u) -- (-.2u,-.25u){dir 135} .. (0, .25u) .. {dir
225}(.2u,-.25u) -- (.3u,-.25u);
enddef;

I will think about it. It is not yet possible.
