help with pyparsing

[Neal Becker]

I'm just trying out pyparsing.  I get stack overflow on my first try.  Any
help?

#/usr/bin/python

from pyparsing import Word, alphas, QuotedString, OneOrMore, delimitedList

first_line = '[' + delimitedList (QuotedString) + ']'

def main():
    string = '''[ 'a', 'b', 'cdef']'''
    greeting = first_line.parseString (string)
    print greeting

if __name__ == "__main__":
    main()

/usr/lib/python2.5/site-packages/pyparsing.py:2727: SyntaxWarning: Cannot

  return ( expr + ZeroOrMore( Suppress( delim ) + expr ) ).setName(dlName)
