I'm confused by the following session at https://beyondloom.com/tools/trylil.html
# This is from the tutorial local x:(list 1,2,3) local y:(list 4,5,6) print[flip x,y] # => 142536 # So far so good local s:"abcdef" local l:"" split s print[l] # => abcdef print[typeof l] # => list print[keys l] # => 012345 local r:random[2 count s] print[r] # => 100111 say print[typeof r] # => list print[keys r] # 012345 # so l and r are both lists with 6 elements each print[flip l,r] # abcdef100111
I expected the last line to show something like a1b0c0d1e1f1. I can't tell what difference there is in the shape of the arguments to the two calls to flip.
