184.108.40.206.2.4 Lambda Forms
A lambda form is similar to a function form, except that
the function name is replaced by a lambda expression.
A lambda form is equivalent to using funcall of a
lexical closure of the lambda expression on the given arguments.
(In practice, some compilers are more likely to produce inline code
for a lambda form than for an arbitrary named function
that has been declared inline; however, such a difference
is not semantic.)
