'dt_select' now can match variables by Perl-style regular expression, e. g. '^Petal' returns all variables which start with 'Petal'.
new functions 'to_list', 'to_vec', 'to_df', 'to_dfc' for convenient lists processing. They have a little pythonic style interface: 'to_list(1:10, if(.x %% 2 == 0) .x)' will return only even numbers. For details see '?to_list'.
new functions 'take_all' and 'let_all' for summarizing and aggregating multiple variables.
