Let's say that I have the following function:
```
void add(T)(T val, T val2) { return val + val2; } // Classic
example, lol
```
Now let's say that I call the function passing an `int`
parameter. The function will get built with an `int` type. What
happens the second time that I will call it again? Will it get
the already build function or will it make a new one? I suppose
it re-uses it but still I wanted to ask just in case. Please only
answer if you are sure and not be making guesses because it is
really important! Thanks!
