assert foo == bar, "foo=$foo bar=$bar";
or (Java-like):
assert foo == bar : "foo " ~ foo ~ " bar=" ~ bar;

 I'd prefer:
 assert foo == bar, "foo=$foo bar=$bar";
 or (Java-like):
 assert foo == bar : "foo " ~ foo ~ " bar=" ~ bar;
 


assert(x==1, "x: %d", x);

assert(testExpression, formattingString, ...);

(I like the parentheses on assert.)

I think adding optional output options on assert would be great. I think 
I'd use it often.

That's a good suggestion. I've spent heaps of time putting printf stuff in
and around invariants this w/e, as I've been working on DTL containers.
Lists were especially assertive ... ;)

Indeed.

Me too.  It's just common sense that assert with printf functionality 
would look like this.  C/C++ programmers will instantly know how to use 
this.
