Done <g>. New alternate-assert module is attached.

Sample usage:

--------------
module nonFatalAssertTest.main;

import semitwist.util.nonFatalAssert;

void main()
{
    FatalizeAsserts();
    // Main program code here
}

unittest
{
    int foo = 2;
    char[] bar = "hello";

    // *REALLY* need a way for a template to automatically get
    // the file/line of instantiation.
    // Improvement to mixin syntax would also be nice
    // Also, my editor doesn't know that backticks indicate a string,
    // so it's still properly highlighted as code :)
    mixin(NonFatalAssert!(__LINE__, __FILE__, `foo == 3 || foo > 5`, "foo is 
bad"));
    mixin(NonFatalAssert!(__LINE__, __FILE__, `2 + 2 == 4`, "Basic 
arithmetic"));
    mixin(NonFatalAssert!(__LINE__, __FILE__, `false`));

    mixin(NonFatalEnsure!(__LINE__, __FILE__, foo, `_ == 3 || _ > 5`, 
"ensure foo failed"));
    mixin(NonFatalEnsure!(__LINE__, __FILE__, foo, `_ > 0`));
    mixin(NonFatalEnsure!(__LINE__, __FILE__, bar, `_ == "hola"`));
}
--------------

Output:

--------------
nonFatalAssertTest\main.d(21): Assert Failed (foo == 3 || foo > 5): foo is 
bad
nonFatalAssertTest\main.d(23): Assert Failed (false)
nonFatalAssertTest\main.d(25): Ensure Failed: ensure foo failed
Value 'foo':
Expected: _ == 3 || _ > 5
Actual: 2
nonFatalAssertTest\main.d(27): Ensure Failed
Value 'bar':
Expected: _ == "hola"
Actual: hello
tango.core.Exception.AssertException at semitwist\util\nonFatalAssert.d(86): 4 
Assert Failures
--------------

Sorry if this comes across as thread hijacking, that wasn't my intent. My 
main point is that in D, we don't have to choose between having detailed 
assert messages and having natural syntax for assert's conditional. We can 
have both.
