So, I accidentally figured this out while playing around with some strings.
(str 111) => "111"
(str 0111) => "73"
What is this?
In Clojure, passing number with leading 0s to str causes strange behavior. What feature is this?

Numbers prefixed with 0 are octal:
0111
=> 73
Numbers prefixed with 0x are hexadecimal:
0x111
=> 273
Numbers prefixed with Xr, where X is number from 2 to 36, have that radix:
2r111
=> 7
If you want to pad number with zeros, see format or cl-format:
(format "%04d" 111)
=> "0111"
(clojure.pprint/cl-format nil "~4,'0d" 111)
=> "0111"
