sudo gem install ParseTree (!!)

% echo "foo [1]" | parse_tree_show -f
...
[:fcall, :foo, [:array, [:array, [:lit, 1]]]]

without any other context to go on, it is assumed it is an fcall, in  
other contexts it could be an lvar, dvar, or a regular call.

You should also do a gem unpack ParseTree and look through the unit  
tests. That might answer quite a few of your questions as well.
