# Some notes on design of filters / sort / regex

do basic (non regex) sort & filter
either sort on a col (up/down), or Dan sort
filter/grep needs a think
out =

#- FIXME refactor for (Num), (Str) == None... (1,2,3,(Int)).are (Int) dd (1e0, NaN, (Num)).are (Num)
#- FIXME accept List for <a b c>
#- imo embedded regex/str ops are unfriendly --- aim for this in raku map/apply -- build on Dan sort/grep
#- imo embedded ternaries are quite unfriendly --- I would rather aim for this in raku map / apply
