Self-contained clojure file with deps

#!/usr/bin/env bash

#! top-of-file comments can be written using more #! lines, which 
#! is a valid comment in both clojure and bash

":";# alternately this works too

#! The construction below uses cross-language syntactic hackery to
#! specify the -Sdeps arg in a part of the file that's interpreted
#! by clojure as clojure syntax (i.e., not a line comment), so it 
#! should get syntax highlighting and other editor support

;; put useful code here

it seems github decides to highlight this as a bash file
