If that's what you want, it's easy enough to create a helper function which 
you use instead of a cast which does the contract check as well. e.g.

char toChar(dchar c)
{
    assert(isAscii(c));
    return cast(char)c;
}

foreach(ref char c; str)
    c = toChar(std.ascii.toLower(c));

It should be completely optimized out with -release and -inline.
