Roeloff,
Is this for the Advent of Code 2018?
The easiest way is to read the input file...  Then, I can guide you from there!

 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 ?

Roelof
