Example

#include <utxcpp/core.hpp>

int main() {
	utx::print_with(utx::Delim{'-'}, "I", "have", 3, "apples");
	utx::print();
	utx::print_with('-', "I", "have", 3, "apples");
	utx::print();
/*
Result:
I-have-3-apples
I-have-3-apples
*/

	utx::print_with(777, "It", "is", "too", "small.");
	utx::print();
/*
Result:
It777is777too777small.
*/

	utx::print_with('-', 'I', "have", "no", "idea.", '\n');
/*
Result:
I-have-no-idea.-

(Because there is a delim between "idea." and '\n')
*/
