That's how i feel about it, people didn't care enough and easiest 
solution picked (let's put this lib instead), now you have to use 
a feature, as a lib, calling functions that looks like template 
functions, in the end it is confusing

i can switch(t), but i can't match(t), i need to use a different 
syntax
