Tempted to add an "Examples" section to the 'help' message. For example:
$ opa run *.json
OPA 0.2.1-dev (commit f56ae0d, built at 2016-11-14T22:38:16Z)
Run 'help' to see examples and list of commands.
> help
Examples
========
> data # show all data and evaluate all rules
> data[x] = _ # show top-level keys
> data.foo.bar # show specific value
Commands
========
<stmt> : evaluate the statement
package <term> : change currently active package
import <term> : add import to currently active module
unset <var> : undefine rules in currently active module
json : set output format to JSON
pretty : set output format to pretty
dump [path] : dump the raw storage content
trace : toggle full trace
truth : toggle truth explanation
help : print this message
exit : exit back to shell (or ctrl+c, ctrl+d)
ctrl+l : clear the screen

I like that, though people might want examples for things besides lookup. And then the examples section might large. But perhaps that's a bridge we'll cross when we get to it.
