here files are still useful because they don't use
memory proportional to their size, so you
can have a 100MB here file without worrying too much.
that's why they don't work in functions (byron's rc
converted a here file within a function into a "here string"
which basically amounted to {echo string | command}
but with the here file syntax; not much point in that,
save for regularity)
