[proposal] version statements with multiple arguments.

[1100110]

Looking at std.io (hopefully the right version maybe?) I see this:

version(OSX)
{ 	do something; }
version(Windows)
{ 	do the same thing as above; }
version(FreeBSD)
{ 	ditto; }
version(Linux)
{	finally do something different; }
and:
version(Windows) version(DigitalMars)
{ 	something; }


I was rather surprised that this wasn't accepted:
//Error: found '||' when expecting ')'

version(OSX || Windows || FreeBSD)
{ 	do something; }
version(Linux)
{ 	do something different; }


The last one could be intuitively described as:
version(Windows && DigitalMars)
{ 	blah; 	}


So I guess in the end I am proposing a change.
A change that I cannot see breaking backwards compatibility while also  
shortening code duplication.
It also seems much more 'intuitive' to me.

version(Windows) version(DigitalMars) {}
made me think twice to make sure I knew what it was doing.

What do you guys think?  If this was implemented, how could it break  
backwards compatibility?
Is something like this worth a change?
Are there any drawbacks to this idea?
