app.config.from_pyfile() is turning values into tuples?

I'm running into something confusing with Flask 10.1.

from flask import Flask
app = Flask(__name__)
app.config.from_pyfile('local.cfg')
app.config.update(dict(
  BAR = 'bar',
))

where local.cfg is

FOO = 'foo'
BAR = 'bar'

I get

app.config['FOO'] => ('foo',)
app.config['BAR'] => 'bar'

Am I doing something wrong that's turning FOO into a tuple?

Well, that was embarrassing. I was suffering a case of comma blindness. For the benefit of anyone else who stumbles into this problem, having a stray comma in a configuration file causes tuples. That is,

FOO = 'foo'

works as expected. But type

FOO = 'foo',

and things go sideways, since app.config['FOO'] == ('foo',)
