Why could we not have?

I asked this up-thread. What was the rationale for let not const binding 
via class declarations? I honestly do not remember us considering const. 
Did we just "default" into let because of the historical (var) default 
binding form being mutable? If so, is it really too late?

Cc'ing Arv in case he can check via Traceur telemetry whether anyone 
counts on let-not-const from class.
