It's hard for me to see how it would be reasonable to not fix it. 
This is one of those ugly parts of the language that need to be 
evolved out of the language. If there's a reason to support this, 
it should be done with a compiler switch. I'm pretty sure that 
this was one of the weird things that hit me when I started with 
the language, it was frustrating, and it didn't make a good 
impression.
