Issue Description:
I had a bug in my code for quite some time that went by unnoticed, because I didn't realize Swift handled octal numbers differently. Specifically I was making the following call
mkfifo(path, 0644)
This should obviously read `0o644`, but went by unnoticed, since it just resulted in an elevated user permission.
It would be great if the compiler could warn in such instances where numbers are typed with leading zeroes, maybe something of the form "Did you mean to write an octal number?"
