Euonymus fortunei or Wintercreeper
Neither of these characteristics make it desirable to have in a harmonious food forest garden. However, the problem remains, what to do when invaded? I didn't buy or plant any, and when I discovered the patch in the first photo, I initially thought I'd solved the ground cover problem for landscaping near the house.
I discovered how dire the wintercreeper invasion could be last winter when wandering about taking photographs.It was in December when all the leaves have come off the deciduous trees, or in the case of some oaks, remain there brown and lifeless. Even the Bush Honeysuckle, invading from Amur, has dropped most of its leaves. But there was this one tree I spotted that still had a lot of green on it. I got closer was completely puzzled by this new kind of vine, at least new to me. Kind people on a Facebook group identified it for me -- the same vine as I'd been admiring as a ground cover can form six inch thick trunks and strangle anything they come across.
Missouri Botanical Garden lists it as invasive, as does InvasivePlantAtlas.org.
Basically cut back to root stem and paint fresh cuts with poison. After frost and before wild flowers start to bloom.
