[Tutor] script still too slow

Hello, Paul!

This version is approximately 30% faster than yours (token = changed
to return, otherwise it doesn't seem to make sense). Cannot suggest
anything better :(

def evaluate_token1(s,t):
    """Evaluate ts. Return a value if the t is not a 
    control word. Otherwise, pass t onto another method
    for further evaluation."""
    if t == '{':
        s.bracket_count = s.bracket_count + 1
        return 'ob<nu<nu<nu<' + str(s.bracket_count) + '<{\n'
    elif t == '}':
        s.bracket_count = s.bracket_count - 1
        return 'cb<nu<nu<nu<<' + str(s.bracket_count + 1) + 'd}\n'
    elif t == r'\{':
        return  'tx<es<nu<nu<nu<{\n'
    elif t == r'\}':
        return  'tx<es<nu<nu<nu<}\n'
    elif t == r'\\': # double or escaped \
        return 'tx<es<nu<nu<nu<\\\n'
    elif t[0] != '\\': # single \
        return 'tx<nu<nu<nu<nu<' + t + '\n'
    else:
        return s.evaluate_cw(t)
