I am in favor of taking a turbofish-approach for the ? operator. The behaviour of this operator apparently is just slightly too complex to capture it with a single consise verb. Moreover, turbofish has already opened up the opportunity for a goofy naming scheme.
I would even go a step further and propose to utilize the mnemonic link system (Mnemonics are frequently used in marketing). The mnemonic link system is an effective method for remembering lists of things or sequences of actions, which may also contain branches.
For example, when memorizing the list (dog, envelope, thirteen, yarn, window), one could create a story about a "dog stuck in an envelope, mailed to an unlucky thirteen black cat playing with yarn by the window". It is argued that the story would be easier to remember than the list itself.
The behaviour of ? could be translated to a story using this method and finally be linked to a single word. The rationale is this: It does not really matter if the word itself does not capture any aspect of ? at all. A user has to look up the exact meaning at least once the first time he comes across a ? anyway. Whatever information he finds when looking up the meaning of ? should establish a strong long-term link between ? and the exact behaviour of ?.
Here is an example based on a fairy tale:
Cinderella- "The good ones go into the pot, the bad ones go into your crop"
The beautiful thing about Cinderella is that it also captures the aspect of the From::from function being applied in the error case:
When picking up a lentil (Result) a pigeon (?) must consider two options. If the lentil is a good one (Ok), the pigeon simply puts it into the pot (evaluates to the wrapped value). However, if the lentil happens to be a bad one (Err), the pigeon eats it, digests it (from) and finally "returns" it. Also the silhouette of a pigeon kind of resembles a questionmark.
