D - $ in identifier names

G'Day,

gcc and old c compilers used to allow $ in identifiers. Personally, I
find this handy as you cannot get a name clash. 

The background is that I have programs that generate other programs
(compile and then run them in the background) from input the users have
given.

For example is a user requests "restrict '$date<20010101'", the program
might generate:

	while( getrecord(in,record) )
	{
	const string $cust = record[0];
	const string $date = record[1];
	:
	if( numeric($date)<20010101 )
		putrecord(out,record);
	}

Just a thought!

I've been leaving that option open by avoiding using $ or   as operator
