Use tabs to align stuff on the left. This means putting some_key_1 on the next line. Also move the closing brace to a new line and add a comma after some_var_3.

Use tabs to align stuff on the left. This means putting some_key_1 on the next line. Also move the closing brace to a new line and add a comma after some_var_3. Added advantage that you can move all of the lines around, :sort them or comment out individual ones without breaking anything. Use spaces to align anything after the key, I usually align them with a tab stop so that several blocks line up. thing = { [->]some_key_1: some_var_1, [->]some_key_2: some_var_2, [->]some_key_3: some_var_3, }
