Speaking of funny shebangs, I came up with this to shell execute prolog .pl files, but it should work for any scripting language that has /**/-comments but doesn't support #-comments or #! shebangs specifically:
/*usr/bin/env scryer-prolog "$0" "$@" ; exit #*/
> The way this works is that this test.pl is both a valid shell file and prolog file. When executing as shell the first line finds and executes /usr/bin/env after searching for the glob pattern /*usr/bin/env. env then executes scryer-prolog "test.pl" which runs the prolog file as a module and halts; of course prolog ignores the first line as a comment /* ... */. Then the shell continues and executes the next command after ; which is exit which stops execution so the rest of the file (which is not valid shell) is ignored. The # makes the shell evaluator ignore prolog comment closer */ to prevent it from printing an error.
This may be the best and worst thing I have ever created.
