Re: [Challenge]How short or efficient can you make this code?

I didn't take time to properly understand your code or to test this, but here's 
my idea of what clean code looks like:
    
    
    import os, streams, strutils
    
    var appendCodeBlock  = ""
    var filesWeAppendTo: seq[string]
    
    let wildcard = getCurrentDir() / "*.nim"
    for file in wildcard.walkFiles:
      if file.getFileSize != 427: continue
      let code = file.readFile
      if code.contains("#marker"):
        appendCodeBlock &= "\n\n\n" & code
      else:
        filesWeAppendTo.add file
    
    for file in filesWeAppendTo:
      let fs = newFileStream(file, fmAppend)
      fs.write appendCodeBlock
      fs.close
    
    
    Run
