[erlang-questions] Printed list to Erlang function
Tue Mar 29 19:52:18 CEST 2016
As noted by Sergej, the issue for me was how to transform the list on the printed page into an Erlang list that I could process further; e.g. how to get from the printed list to stopwords/0 with minimum steps along the way.
My efforts were taking from copy into file, read back into binary, convert to list, use string:tokens/2 to transform newlines of commas, yada yada... until I had a list in the Erlang shell. But, then, how do I move that list into module? I could do it with another search and replace, but in all, it felt ugly.

Wow. Some serious copy-paste snafu my mail client was smart enough to
render invisible to me, but dumb enough to pass on to the world.
I intended to paste the following:
