True, one ought to say "drop -1 coin from the table" => "let me view the
coins on the table, but hide -1 of them" => "show one of the previously
hidden ones". "take -1 coin from the table" would be more like "let me
view the coins on the table, hide all but -1 coin".

There is nothing good about any of this, I prefer the assumption that I
get 5 and only 5 when I ask for 5. I guess that is too conservative, eh?
