Sorry, it would not be welcome. Single letter names are appropriate for locally 
defined symbols. There's also an informal naming convention for them, changing 
the names would disrupt that.

Shuffling code around without a very strong reason is also not looked upon 
favorably. Basically anything that vacuously creates large diffs.
