What if your lambda contains a single function call in parentheses, like this:

  lambda(a) (myfunc(100, a))

Say myfunc() returns 3 values. Should they get truncated to 1 value by
the lambda? Parentheses around a function call will ordinarily
truncate it to one value - but that is confusingly at-odds with having
optional parentheses around lambda return values.

Simplicity is not so easily achieved :)
