The version in Pharo is called #reduce: and slightly slower, but also more  
general. In Pharo not only two-argument blocks are supported, but also  
blocks with more arguments. Furthermore, for sequenceable collections there  
are variations for left- (#reduceLeft:) and right-fold (#reduceRight:). I  
suggest to keep the Pharo versions.

Thanks for your feedback.

may be should just integrate

+ copyUpThrough: anElement
+       "Answer all elements up to and including anObject. If there
+       is no such object, answer a copy of the receiver."
+
+       ^self first: (self indexOf: anElement ifAbsent: [^ self copy])

#fold: is sent by the Cog VMMaker code, so you either implement it,
modify the Cog VMMaker code or you won't be able to build a Cog from a
Pharo image (building such an image is a tedious task anyway).

We will encounter (and fix) these things when we do the VM auto-build setup.
Maybe we then just load a pre-load for things like that.
