do I incur a penality on compile time if I explicitly declare default behavior ?

Furthermore, regardless of the impact, one of the pros of 
explicitly coding like this is to help future-portings of the 
base code to another language if need so, the team porting the 
code won't be required to be knee-deep on the language 
whereabouts of the code being ported because the obvious is 
already stated in the code itself. The team won't need to know 
beforehand that in D everything inside a structure/class is 
public by default for variables declared without scope modifiers 
etc etc.

But, as a footnote, of course I am thinking the other way around: 
just tinkering with the idea of porting things into D and not 
away from D :)
