I'm impressed.

Comment: It seems amazing that even as languages get more and more
powerful, we seem to spend more time pushing strings through hoops.

I've been using '?' and '!' on the end of some methods - NOW I'm
appending things to the method names to break ties.  I am converting
from sym to s, remove the /?!/ and so on and I'm rather on strange
ground exactly where my app is the most prone to serious performance
degradation. So this has been on my mind some.....

Then, following this thought I just read up on "Fancy" (shhh!) (while
reading up on new Wiki features) and was thinking about if there might
a way to use some of that for really "core" stuff.

I'm really happy with Ruby performance so far,  but it could be a
factor coming up, and it seems to be a ok idea to keep an eye out for
ways to tweak performance?


Any comments on converting Symbols to Strings, doing things on them,
then converting back - is there some better way?
