One of my biggest design gripes with D, hands down, is that
functions are
virtual by default. I believe this is a critical mistake, and
the biggest
one in the language by far.
My understanding of this is that while all of your class functions
will be virtual by default, the compiler will reduce them to
non-virtual unless you actually override them, and to override by
mistake is difficult because you have to specify the "override"
keyword to avoid a compiler error.
Thus successfully eliminating non-open-source libraries from D...
Making a dependency on WPO is a big mistake.
final class Foo{ //no inheritance
final: //no virtuals
...
}
2 extra words and you are done. The only problem I see is that there is
no way to "undo" final on a few methods later...
