Golang can be very dynamically also without “reflect” package

My first ambition was to create a method where you can call a function dynamic with his ‘string’ name. The next step was to extend it so that it accepts all types as parameters. The examples show you:
How you can call a function by a name, how you can pass a different count of parameters with different types and how you can use these methods to build a general addition function and logger function. I hope i could encourage you to learn more about all the nice features behind golang and especially that you don´t always falling back to “reflection” when you want to go dynamically.
