[Pharo-users] How to take care that the + before a number is ignored

[Roelof Wobben]

Hello,

I have a collection that looks like this :
sampleData1
    "comment stating purpose of message"

    ^ #( -8
    +7)

I want to add those numbers up but the code chokes at the +

so I did this :

FrequencyFinderData  new class sampleData1   inject: 0 into: [:sum :each 
| (each ~= $+) ifTrue: [sum +  each asInteger] ]

so when the each is not a +  it must count it but still the code chokes 
at the +

Where do I think wrong ?
