Last case of Issue 710 in the internal repo:

like = Box('like', n @ n, n @ n)
x = Box('x', n @ n @ n, n @ n @ n)
y = Box('y', n @ n, n @ n)
z = Box('z', n @ n, n @ n)
alice = Box('Alice', Ty(), n)
tuna = Box('tuna', Ty(), n)
it = Box('it', Ty(), n)
blank = Box('', Ty(), n)
w = Frame('and', n @ n @ n, n @ n @ n, components=[
    x, y, z, z
])
doesnt = Frame('doesn\'t', Ty(), n @ n, components=[
    like, like, like, w,
])
diag = (n @ alice @ n @ tuna @ doesnt @ it @ blank @ n @ n)
diag.draw(figsize=(12, 12))
