While I appreciate the suggestion, this makes it less consistent with the language we use elsewhere.

An alternative that could maybe work is to rename the variables to nodeA and nodeB to distinguish them more from the leading "A". WDYT?

[zhangenming]

how about use 'the' word

[zhangenming]

this makes it less consistent with the language we use elsewhere.

Either solution seems to require global modification

[annevk]

"The" has the same issue as removing "A". I'm not sure what you mean with global modification for my solution? I don't think there's that many variables named "A"? Or perhaps I misunderstood the problem?

<var>A</var> search result : 44

a node a // strange
a node nodeA // redundancy
the node a // better
node a // best

Whichever option is chosen
Will causethis makes it less consistent with the language we use elsewhere.
So i think the whole thing needs to be revised
