Is it possible to use templates to implement something like the `@show` macro from the Julia programming langauge in D?

Thank you all for your very helpful replies and for taking the 
time to make them!

It is indeed heartening to see that D supports multiple different 
forms of this mechanism.

This is certainly sufficient for the example I gave.

I suggest that something like this should be added to the 
standard library and perhaps even shown in early examples in the 
tutorial and documentation. Such things are so routine that I 
would argue that it should be the most common form of print-based 
debugging. It also seems to be becoming an expected/standard 
feature among new languages too, for obvious practical reasons.

The prospect of using D does look brighter now, knowing all this.

More specifically, I am planning to do a combination of general 
application development, game development, and eventually 
building a language transpiler of my own (for which I've been 
gradually coming up with ideas for over the years). I have grown 
tired of dealing with C and C++'s mess and build ecosystem.

D's expressiveness is adequate now that I know what you've all 
said here.

I am debating between D, Nim, Zig, and Rust. Each have pros and 
cons, although all are clearly great and none would be "bad" 
choices (barring unexpected events).

I will consider it for a while longer. I want a stable platform 
to build on long-term that is also flexible and pleasant to work 
with.

So, tangentially, I'd also be interested in hearing any of your 
all's thoughts about that regarding D (and/or the other 
prospective languages).

Thanks again for reading and for the fast and extremely helpful 
replies! It is much appreciated! I wish you all a wonderful 
day/night/week/etc!
