That was what I came up to myself, more or less, but I thought I was overlooking a tacit construction.
You know perhaps the puzzles of trying with a few given numbers to build another given number by using only elementary mathematical operators and an arbitrary amount of (matching) parentheses. So, e.g. how can 1 3 4 6 give 24? (give it a try) I came up with all the 120 possibilities of the 3 combinations out of 6 possible elementary operators to insert between all the 24 possible combinations of the 4 numbers. And then wanted to evoke gerund `: 3 for every gerund to every combination and check the output. So (4 :'x`:3 y'"1"_ 1) does the job. R.E.
