I think that eval just gives access to ruby interpreter itself in run-time. 
How could it behave differently from ruby then, if it _is_ ruby? That's just 
a needless ambiguity.

You can just do p "#{a.inspect}", as it works great with strings, arrays and 
hashish..oops..hashes :). Or you always can define a method, i.e. to_evil in 
String, Array, Hash, or in any other class you use in eval, and use it like 
#{a.to_evil}. 
As I see it, it's just ten lines or so. 
You can't change ruby behavior for things just to make it more comfortable for 
you, sometimes you have to change the way _you_ do it.
