Does that only apply to list comprehensions? It seems, from doing some
timings, that just writing raw Erlang to process a list is still
significantly faster than doing a map or fold, for example.  It would be
kind of nice to have certain cases of map be handled as parse
transformations rather than calling lists:map.  Most times I use higher
order functions as sort of a shorthand as it is, and not anything fancy.
