Create idioms by mashing up old ones! Nothing new under the weather.
A text file with each candidate on a separate line
mashups_for_seq_with_lines returns a set
lines = lines_from_path('some/save/path/here.txt')
mashups = mashups_for_seq_with_lines('and', lines)
Run prompt_loop(9) to start a user input loop
in which you select a candidate sequence and see up to 9 (or
any #) randomly chosen mashups pivoting on that sequence.
