You don't need to create a new sequence inside the function: you can just use
srcSeq, like this:

sequence s1

global function seqConcat(sequence srcSeq, object toAppend)
  for i = 1 to length(srcSeq) do
    srcSeq &= toAppend
  end for
  return srcSeq
end function  --seqConcat()

s1 = seqConcat({"abc","def","ghi"}, '\n')
