Of course, let expressions would need lambda-coding no matter what
names were shadowed. The experience gained in JS1.7+ shows more let
block usage than let expression, but expression temporaries (lacking
macros and ignoring automatically generated code) are uncommon in
today's JS. The function-expression-immediately-applied cliché usually
has statements for effect, if not a return -- not a single expression
in its body.
