I have tried variants of the above but I'm not getting quite what I
want. I actually need to know when the call starts with the Project
(shown below) because it is the object which contains the Map of values
I would like to interpolate into the String.

I figured I would need a flow construct of some sort. I'll keep
experimenting!

In short, man creates for himself a new religion of a rational
and technical order to justify his work and to be justified in it.
