Uses same rule as jq math functions, 1 arg uses input, more than one all passed as args. So "bnot 1" -> "1 | bnot", "1 bsl 1" -> "bsl(1; 1)" Don't think it's worth changing the jq syntax for this and also it could make fq scripts no compatiblr with other jq tools. Non-10 base number literals are still allowed but should probably not be used in scripts, only in repl and with cli.
