sibling: vs. fileexists:

[NotNull]

I noticed that fileexists: is quite a bit faster than sibling.
Would it be possible to equip sibling: with the same turbo-engine as fileexists:?

[void]

sibling: does a partial search. (slow)
fileexists: does an exact lookup.

I have put on my TODO list to optimize sibling: when a simple filename lookup is specified.
Thank you for the suggestion.

Thanks!

(it has been a while, but I think fileexists:*text* was faster than sbling:text too. Not sure though..)
