That's just conditioning. If you are used to "BEGIN" and "END" 
picking up braces takes time, same time the other way around. If 
you use single item per line and a proper IDE they aren't really 
different. Python's indentation the same, but you need a decent 
IDE that does proper re-indentation etc.
