I think Michel and Shawn did raise some good points here.

> I also am having difficulty coming to terms with the use of "form" (I am a native English speaker). As you note "form" can imply the creation of something from parts (more like assembling a new thing) as well as the creation of something out of a material say a of block clay (more like molding something out of an existing thing). It doesn't seem clear cut to me to imply in place mutation.
> Additionally my eyes / brain keep seeing "from" instead of "form". This type of issue is generally true with any short word made up of the same set of letters (made worse since "from" is more common in programming then "form"). The mind quickly narrows in on a set of possible words given the letters we see and then uses context to help get the correct one and/or additional visual parsing to understand the exact ordering of letters (more energy expended). Anyway since I keep seeing "from" instead of "form" I keep going in the direction of thinking it returns something made from the two (or more) items involved (not really sure why "from" goes that direction in my head, it could also go the in place direction).
> I would prefer something other then "form" (note I just typed "from" by mistake)... I think your suggestion of "become" has merit.
