This is a creeper growing on the fence of the vacant lot opposite.

It might be a kind of gooseberry. See those pyramid shapes toward the right there? They’re a papery, poofy shell with seeds inside. Maybe physalis minima or pokok letup-letup (letup = explode)?

Or it could also be a young passiflora foetida (passion flower vine). 

Btw, check out Dr Francis Ng’s excellent blog Tropical Gardening. He’s also the author of Tropical Horticulture and Gardening, a true gem of a book. My mom gave me a copy, and it’s been an awesome roadmap into the weird wonderful world of Malaysian plants.
