Oh crap, I shouldn't have opened my big mouth.

My statement about making formal parameters implicitly final wasn't a proposal, 
nor did I intend to reopen this conversation. It was a flip comment based on a 
stylistic pet peeve of mine.

Turns out this was discussed extensively last year on lambda-dev in a thread 
started by Venkat S. [1] I either missed this or had forgotten about it. There 
were a fair number of people who thought it was reasonable, but there were 
questions about how beneficial it would be, plus there was the usual fractal 
graph of related and dependent issues. I suggest people go reread that thread.

Sorry for the noise.
