`$_` is the default variable in perl (or was).  I can potentially 
envision people using `_` as an iterator, match result, bitfield 
padding variable, etc.  Whether that's a big enough issue worth 
worrying about, eh.  Though it does seem odd have to make the 
exception "`_` is a word character, you can use it in any symbol 
name, except by itself."  Suppose that's essentially the same 
situation for keywords, though.

Is `..` used anywhere besides slicing and `foreach`?  Just 
throwing that onto the pile, though it's probably another 
tool-breaker.
