String mixins are fun, but you could also use a more classic

void main() {
string s;
checkNonNull!s;
}

Or with file and line:
---
void checkNonNull(alias var)(string file = __FILE__, size_t
line = __LINE__) {
if (var is null)
throw new Exception(var.stringof ~ " cannot be null.",
file, line);

Good point! Alias parameter for the win!
With this, there is simply no reason to use a mixin.
