In this thesis, Hughes showed that by doing lambda lifting in a particular way, a useful property called full laziness can be preserved (Hughes [1983]). Full laziness has been seen as intertwined with lambda lifting ever since. We show that, on the contrary, full laziness can be regarded as a completely separate process to lambda lifting, thus making it easy to use different lambda lifters following a full-laziness transformation, or to use the full-laziness transformation in compilers which do not require lambda lifting. On the way, we present the complete code for our modular fully-lazy lambda lifter, written in the Haskell function programming language.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An important step in many compilers for functional languages is lambda lifting.
