... and "const a(){}" or "let const a(){}", which are what you would
want in preference to "var" or "let" in the majority of cases for
function definitions.

(Is it just me, or is "let const" as proposed in
<http://wiki.ecmascript.org/doku.php?id=proposals:block_expressions>
a bit too verbose? E uses "def" for constant declarations, and IMHO
it does matter that this is just as concise as "var".)
