History aside, my preference would be what E does: A variable is in
scope textually starting at the point of declaration, left-to-right,
until the close of its enclosing scope block. I would love it if this
applied to lets, consts, and functions. However, given that ES3
functions hoist (within the top-level function body), I think the
least surprising least asymmetric compromise is to generalize
functions to be per-block, and to have const and let scope like
functions will.
