i like numbers. `r print_num(5)` is a number

another number i like is `r x`.

Here is another number: `r print_num(x)`

That works fine. the object `x` is available within inline code chunks.

What happens if it is set as a default arguement?

in a code chunk 

```{r}
print_num_x()
```

the same is true for an inline code, but why break something twice?
