[OpenSCAD] "Melting" models

The operation that is being discussed here is often called "bend", and it bends a shape around a cylinder. It's a useful general purpose CAD operation, and it's strange that more CAD programs don't include it. A simple example is adding a bend to a pipe. I often use it for bending long skinny objects into rings.
Another "plastic deformation" that I get a lot of use out of is "twist".
Here's an old SIGGRAPH paper that makes the case for including "bend" and "twist" in CAD programs:

Soften in boiling water, or apply a heat gun, or just print in black+leave in sun (I learned this last one the hard way a few years ago when I left a Prusa i2 printer in the hatchback of a car for one Texas summer day, with black PLA used for the frame vertices)
