Hands-On Design Patterns and Best Practices with Julia

Interpolating in nested expressions

It is possible to have a quoted expression that contains another quoted expression. This is not a very common practice, unless the programmer needs to write meta-metaprograms. Nonetheless, we should still learn about how to interpolate in such a situation.

First, let's recap what a single-level expression looks like:

We can wrap the quoted expression with another quote block in order to see what the structure of a nested expression looks like:

Now, let's try to interpolate in such an expression:

As we can ...
