Remember that if this matters to you, you can "from math import inf".
But you still need to use full eval on your repr, which could be a serious security problem in some contexts. If it were a built-in constant, ast.literal_eval could be used instead.
Perhaps the real solution is for literal_eval to be given a specific set of names that it's allowed to reference. Most things don't have to be keywords - it's normally fine for them to be builtins. (Or, in many cases, importables.) If you make "inf" a keyword, then even the Python standard library is broken.
