Because the question was how to write the example in ES, not how to
write it in ES using only functions.
The result was in fact very readable code which IMO looks better (if
one forgets the loop stigma) than both function(name) expr and name =>
expr versions. That plus those Y-combinator examples tells me that in
fact name => expr or (\name) expr as syntax sugar are not sufficiently
sweet to justify their existence compared with function(name) expr.
