The code (lambda (x, y): x)((3, 5)) fails because
the passed-in tuple is not unpacked into the arguments.

Investigating lambda behaviour, as per comment on 1190011

After looking in all the wrong places, it turned out to be something
simple in the compiler. I factored out the relevant code from the
function compilation, so that lambda compilation can use it too.

Assigning to Brett for review.
