The following snippet works (fresh [?row ?col] (fd/+ row 1 ?row) (fd/+ col 1 ?col) (membero {:row ?row :col ?col} data)))] ; check existence of {:row (?row + 1) :col (?col + 1)}
But I'm not sure if this isn't to verbose. The question is: Is it really neccessary to bind to row and col or ist there a shorter way ?
