Overview of the Issue

The Expressions documentation at https://developer.hashicorp.com/packer/docs/templates/hcl_templates/expressions talks about "conditional evaluation" in a couple of places. But nowhere in that documentation or anywhere else in the Packer documentation do they give examples of or say how to do conditional evaluation. To me, conditional evaluation means logic that determines a value, something like C's ?: ternary operator or Python's foo if bar else baz conditional operator syntax. There is no such thing in Packer. The documentation should not claim there is and then not say anything else about it.

Reproduction Steps
