How to launch gedit from terminal and detach it (just like "subl" command works)?

To open a file to edit in gedit I run gedit sample.py &. But with Sublime Text it is simply subl sample.py. This opens the file to edit and it doesn't run in the background (in my shell). How would I do that with gedit? I tried exec /usr/bin/gedit "$@" (copied from /usr/bin/subl) but it works like gedit &. Or alias ged="gedit $file &" should do. What can I substitute $file in the alias?
