configobj validation

[Andrea Crotti]

I seemed to remember that type validation and type conversion worked out 
of the box, but now
I can't get it working anymore.

Shouldn't this simple example actually fail the parsing (instead it 
parses perfectly port to a string)?

sample.py:
from configobj import ConfigObj

conf = ConfigObj('sample.conf', configspec='sample.spec')

sample.conf:
port = some_string

sample.spec:
port = integer(0, 10)

PS. using configobj 4.7.2
