Classification:Other Bug Reproducible:Always
 
Summary:
When attempting to create prefix or postfix operators involving `<`, or `>`, the compiler emits an error.  The grammar doesn't appear to forbid the definition of these operators and there is no conflict in the STL.  I believe these operators should be user-definable or a better explanation provided as to why they cannot be defined in the first place.

Steps to Reproduce:
1. Attempt to define prefix or postfix `<` or `>`.

Expected Results:
The compiler allows `<` or `>` to be defined in prefix or postfix form.

Actual Results:
The compiler emits an error specifically forbidding the declaration of these operators.

Version:
Xcode beta 6.2 (6C86e)
