For me, this is the default as well, meaning locals are constant. I would love it to be the default for the language (or an option to set it so), so that one would declare local _variables_. Which is never needed, and even shows bad practice, except for symbols assignmed in loops, as you say.
This extends to _value_ parameters, which are just locals as well (in other words, "in" is the default for non-referenced parameters).
