[Newbies] another "best practices" question - inject

The "Inject:Into:" pattern in "Smalltalk Best Practice Patterns" says  
"Call the block arguments sum and each." That seems crazy! Why would I  
name the first argument "sum" if I've trying to do something other  
than sum the values? The example the book gives is the following.

^self children
	inject: 0
	into: [:sum :each | sum max: each]

I think I'd do this.

^self children
	inject: 0
	into: [:maximum :each | maximum max: each]
