Something something named arguments

lolif.m

struct ifparams {
#if __has_feature(objc_arc)
	__unsafe_unretained
#endif
	dispatch_block_t then, otherwise;
};

static inline void iff(bool condition, struct ifparams params) {
	((condition?params.then:params.otherwise)?:^{})();
}

#define if(condition, ...) iff(condition, (struct ifparams){ __VA_ARGS__ })


int main(int argc, const char * argv[]) {
	if (5 > 3, .then = ^{
		printf("I can't remember why I'm doing this\n");
	});

    return 0;
}

Oh yea, I forgot #define else otherwise.

And without native control flow:

static inline void iff(bool condition, struct ifparams params) {
	dispatch_block_t c1[] = { params.otherwise, params.then };
	dispatch_block_t c2[] = { ^{}, c1[condition] };
	c2[!!c2[1]]();
}
