Hi Ruby-rulez !
I often look at some code, for example un rails/active_record, where
functions name end with a ? or a !
Is this a special notation, meaning that the func or args or whatever
have some treatment before/after the body ? Or to show that the function
return a boolean (?) and the arg modified (!) ?
Thanx
