Poll: Would you like to try const-by-default or not?

[Craig Black]

I prefer const-by-default for function parameters.  More often than not, 
parameters should be const, so it makes sense to make them const by default.

I think the argument against const by default is that it is not orthogonal 
because function parameters would require a different syntax than other 
variable declarations.  I disagree with that argument because I think 
function parameters are different enough from other kinds of variable 
declarations to justify a different syntax.
