I thought at first that include-file didn't work yet, but it
apparently works if I omit the quote in the filename string.

Maybe you could make compiling/loading files more consistent in a next
LFE update, because the current situation seems to be like this:

(include-file "filename.ext")

(c '"module.erl") or (c 'module)

(slurp '"module.erl")


I currently tend to forget what convention to use when using one of
these functions :-)

Best,
Vincent
