Why does the empty path constant look like an anchor?

[Underflow]

Okay, it's a silly question... but a friend asked and I really have no idea.

Anyone?

A (wild) guess...
... someone at NI handling this part of LabVIEW development , wanted the closest representation of ":\" (as c:\ in dos/windows root path), but wanted dots to be highlighted as well 😉

A (wilder) guess, too:

Perhaps, it isn't an anchor. The upper shape is not filled with colour, therefore empty. The other shapes are filled and all of them are connected by wires of which the one to the empty path is crossed out.

But most likely the guy at NI that made this was an impassionated sailor...
