    I needed to mark specific classes with main support, I could have used a 
different implementation to find out about it like duck typing, or reflection 
etc but these are either not permitted (eg. scala style) or are too complex. It 
is not bad to tag a class that way. Maybe sound redundant even funny (I would 
not call that way) but it serves a purpose to make things easily testable.
