I also forgot to mention, "to" is so much more universal, that it stops
being very useful. If we rewrite my contrived example as...
func rename( fromName="index", fromEx="html", toName="converted",
The we have labels that I can easily imagine the programmer might want to
search code for, or plug in to a second, similar function. I can imagine
working on a file and thinking "what other functions did i use here that
change an extension" - searching for "toExt" is helpful there, whereas I'm
not sure why I would want to find "to[Anything]." I also find it helps me
understand what functions do, when I'm browsing suggestions from code
completion, but that's only my opinion for me to make, so it's hard for me
to make a convincing argument.
