Re: [Python-Dev] anomaly
In case the example given at the start of the thread wasn't interesting enough, it also works in the other direction:
class str(int): pass
str('2') 2 #<----- an integer!!!

Here's something that might be wrong in Python (tried on v2.7):
class int(str): pass
int(3) '3'
What's so odd about this? "class int" is an assignment to "int", i.e. what you're doing here is basically: int = str int(3) # really str(3) * Mark Rosenblitt-Janssen <dreamingforward@gmail.com> [2015-05-10 19:14:18 -0500]:

Same thing. You're shadowing the builtin. Florian -- http://www.the-compiler.org | me@the-compiler.org (Mail/XMPP) GPG: 916E B0C8 FD55 A072 | http://the-compiler.org/pubkey.asc I love long mails! | http://email.is-not-s.ms/
