[Pharo-dev] perform:withArguments: and collection

[Peter Uhnak]

Hi,

Apparently sending #perform:withArguments: and using OrderedCollection leads to 
PrimitiveFailed.

I can recast it, but maybe we can just add

(argArray isArray)
        ifFalse: [ ^ self error: 'Arguments must be instance of Array' ]

to make the error less cryptic.

(or allow OrderedCollection, but since the operation is done in VM it might be 
needlessly more work.)
