nre, am I using it wrongly?

[vsajip]

Looking at a simple problem - find the indentation of text in a line and see if 
it's a comment. Nim version:
    
    
    import nre
    import strutils
    
    let commentChars = {'#', ';'}
    let nonspace = re"(\S)"
    let line = "    ; abc "
    
    var m = line.find(nonspace)
    if isSome[RegexMatch](m):
      let theMatch = get[RegexMatch](m)
      let isComment = theMatch.captures[0][0] in commentChars
      let pos = theMatch.captureBounds[0].get().a
      echo "$# $#" % [$pos, $isComment]
    

Python version:
    
    
    import re
    
    comment_chars = {'#', ';'}
    nonspace = re.compile(r"(\S)")
    line = "    ; abc "
    
    m = nonspace.search(line)
    if m:
        is_comment = m.groups()[0] in comment_chars
        pos = m.start(0)
        print("%s %s" % (pos, is_comment))
    

Not hugely different, yet the Nim version just seems harder to grok. Am I using 
`nre` suboptimally?
