Squeak 3.7 ish -
I've got this meta model that stores attribute names as symbols.

I frequently derive labels from the attribute names and this often  
ends up calling #capitalized on the symbol.

I generally figure any string manipulation on a symbol results in a  
string but Symbol>>capitalized is implemented as

capitalized

	^self asString capitalized asSymbol

I found this while watching the process browser running a lengthy  
script in the background and found about 80% of time was spent in  
WeakSet scanFor:

I did a search of the image and couldn't find a single instance of  
sending capitalized to a symbol where the caller was going to use it  
as a symbol rather than a string.

So, in the name of performance, I vote to nuke this method or change  
it to just return a string.
